The Record 63 Seconds Fast

00:20. I did not erase the four characters written on my wrist.

4. O. Kang. Question mark.

The ink belonged to this loop. When the next reset comes, it will be gone. Still, inside today it works as a baseline. The scrap of paper that had been in O Sejin's hand is gone, and Kang Taejun's handkerchief is folded somewhere, clean. To hold on to vanished physical evidence for long, order works better than words.

I did not write it on paper. Anything anyone can see, I have to explain. So I built a thirteen slot ledger out loud instead. One is door 4, two is O Sejin, three is Kang Taejun's envelope, four is the 00:07 administrator command. Five through thirteen I left empty. Blank slots are records too. Space kept open so that I do not fill in what I still do not know.

I did not set my personal wristwatch to the central broadcast.

Yesterday morning I ignored the automatic sync alert. The wristwatch read 00:20:42, and the handheld terminal displayed 00:19:39 on central network time. The difference was 63 seconds. Once, on its own, that is nothing. The device could have run slow, or I could have set the time wrong yesterday. So I needed three baselines.

I unplugged the digital clock on the desk in my quarters. The digital clock was tied to the central network. Pull the plug and the screen died. It could not serve as a baseline. The small waterproof clock inside the bathroom had no second hand. Minutes alone will not catch 63 seconds. What was left in the end was the wristwatch, the cafeteria wall clock, and whatever independent test rig Go Yura could build.

I started to pull the crown on my wristwatch and stopped. Set it and the baseline disappears. It has to stay not as a wrong clock but as a clock that differs from central. I did not take it off. I turned it to the inside of my wrist. To anyone watching, it could look like hiding the time. If Kang Taejun sees it, he will suspect more. Even so, the baseline had to stay attached to my body.

At 07:35, in the corridor on the way to the cafeteria, the ceiling speaker gave its warning tone. I looked at my wristwatch, and 63 seconds later the broadcast announced breakfast. Second confirmation. Still only the central broadcast was late. The corridor cameras would be on the central network too, so they most likely shared the same lag. Records tied to central cannot prove one another. They can all tell the same lie.

08:11:57. In front of the cafeteria coffee machine, I looked at my wristwatch.

08:11:57.

In the black glass above the coffee machine, a white coat showed up first. O Sejin was closing the door on the reagent room side. His right thumb rubbed the handle of his bag. I raised my eyes to the ceiling speaker.

08:12:00, wristwatch.

The speaker did not sound.

No Eul was tidying cups behind the counter. He was not at an angle where he could see my mouth. Instead he glanced once at the small analog clock on the wall and turned a cup handle inward. That clock read 8:12. It is the cafeteria's independent clock. No cord, and a battery cover on the back.

08:13:03, handheld terminal.

The ceiling speaker spoke.

"Current time, 8:12. The typhoon alert level is maintained."

I did not pick up a cup. My wristwatch and the analog clock were already past 8:13. Only the central broadcast was 63 seconds late. The reflection in the coffee machine glass, O Sejin's path, the direction of No Eul's cup, all of them moved before the central broadcast.

No Eul pushed his letter board over.

`Waiting for another cup to break?`

I wrote something short.

`Checking the clocks. Have you ever set that wall clock yourself?`

No Eul looked at the wall clock and shook his head.

`I only change the battery. The time has been like that since the cafeteria opened. If it's wrong, the customers say so first.`

That answer was exact. No Eul did not talk about a broadcast he could not hear. He talked only about the battery he had touched and how the customers reacted. The wall clock was outside the central network.

I wrote on the board again.

`Did anyone touch that clock this morning?`

No Eul looked at the shelf under the clock. The dust on the shelf lay flat, with no fingerprints. He pressed a fingertip into the dust and left a small gray dot beside the board.

`Nobody touched it. Touch it and the dust breaks.`

He offered dust instead of words as evidence. It was not some psychic feat of observation. It was the answer of a man who cleans every day and knows where he has not cleaned. I put that into the fifth slot on my wrist. Wall clock independent. Confirmed by No Eul.

Yun Haewon was sitting at the third seat by the window. In this loop he did not move his cup on purpose. The right pocket of his jacket still sagged a little. He watched me check three clocks and asked:

"Does time come before people today?"

"Today time moved people."

"That sentence leaves plenty of room to dodge responsibility."

"That's why I'm narrowing it down to numbers."

Yun Haewon did not ask more. He knew how to save a question. Instead he turned his cup handle inward. It was the direction No Eul had already set. The habits of the living repeat. The central broadcast may be late, but hands are not.

09:40. In the control room, Go Yura cut me off three times.

"Central sync is 63 seconds late?"

"Only on devices dependent on the central network."

"So not all of it, part of it. If it's part of it there should be a fault report. If there's no fault report it's observation error. And if it's observation error, then I'm taking the blame before I've even had my coffee."

She talked fast, but she had a direction. It was not that she trusted the institute's systems. She trusted the logs that would remain if the systems were wrong. I had to use that.

I showed her the wristwatch, the cafeteria analog clock, and the photos from the handheld terminal, one after another. Photos belong to this loop and can vanish, but for now they were enough for verification. I had captured the reflection in the coffee machine's black glass along with the broadcast time. Go Yura opened the file metadata before the photos.

"The device that took these is hooked into the central network."

"That's why I brought two independent baselines with it."

"If you want to call something independent you need a device with the network cut. Wristwatch, accepted. Cafeteria clock, half accepted. Handheld terminal, disqualified."

She typed fast. The sync log opened on screen. The 08:12:00 entry was stamped normal. The word normal was no longer safe.

"What if a normal log gets stamped 63 seconds late?"

"Then it's a late log wearing the name normal. In human terms, the type who shows up late and insists his own watch is right."

She said it and immediately grimaced.

"Retract the analogy. Technically, the dependent devices that follow the central baseline all slid together."

"Typhoon interference?"

"A typhoon would scatter them. All of them at exactly 63 seconds means somebody lined them up."

For the first time she looked at me properly. It was not a trusting look. It was the look of an engineer who had gotten interested. That much was enough.

10:10. In the test bay, Go Yura brought out a small test rig.

It was a black plastic box. Connect it to the central network and it sets its time automatically. Disconnect it and it runs on an internal battery. She started to say the equipment's full name and stopped halfway.

"In plain terms, a clock that lives alone."

"Let it live alone, please."

"I don't like the way you put that, but fine."

She plugged in the central cable. The screen showed 10:10:00. When she pulled the cable, 10:10:01, 10:10:02 ticked past. It matched the wristwatch. When she connected it to the central network again, the screen blinked once and dropped to 10:09:03.

63 seconds.

Go Yura did not swear right away. Instead she pushed her chair back and saved the log. Her hands moved fast, but they were hands trying to preserve, not erase.

"Again," I said.

"I know."

She switched the rig off and on. This time she did not attach it to the central network first. She started it on the internal battery. After matching it to my wristwatch, she connected the central cable. The screen slid backward again. 63 seconds. Go Yura pulled the cable and connected the rig to the control room's auxiliary terminal instead. The auxiliary terminal was also dependent on the central network. Same result. 63 seconds.

"That makes it an internal baseline, not the typhoon," she said.

"What about external time?"

"Ordinary comms are dead, so we can't check directly. If Bae Junho's weather link opens we could pull an external baseline, but if I suggest using it now we both get chewed out."

Even while she talked she saved the result files as three separate ones. `independent_start`, `central_attach`, `aux_attach`. The names were not long. They were names that would tell Kang Taejun the order too, if he saw them later.

"Why don't you just delete it, Go Yura?"

"To see whether I was wrong. Delete it and I won't even know if I won or lost."

That was a good answer. Someone who trusts records but does not use them only in her own favor. It was an attitude Ihyeon loses easily.

"This is not a fault."

"Why not."

"With a fault the equipment cries that it slipped. Right now the equipment accepted central as normal. Either someone made central late, or someone made it believe a late central was the real one."

"Who did."

"If I say that now it's fiction. I need to look at more logs."

She stopped and looked at me.

"But why 63 seconds, of all things?"

"I don't know yet."

"Good. Someone who says they don't know can still work with me."

That sentence was not trust but a temporary permit. Go Yura turned the rig's screen toward me. The central time, 63 seconds late, glowed blue. Numbers are narrower than feelings. The narrower they are, the fewer places there are to run.

11:00. In the security office, Kang Taejun laid out O Sejin's alibi again.

O Sejin had been in the cafeteria at the 08:12 central broadcast time. The official camera footage looked that way too. Access to the reagent room was logged from 08:10:58 to 08:11:40, and the broadcast sounded at 08:12. Until now I had believed that order exactly as given. Even though I had seen the white coat appear in the black glass first, I had accepted the broadcast as the baseline.

Correct for 63 seconds and the reagent room access actually came at 08:11:?. Pull the numbers in the central record forward to real time, and O Sejin could have closed the reagent room door and walked into the cafeteria before the broadcast. Conversely, the official alibi was empty by exactly 63 seconds.

I drew three lines on the security office whiteboard. The top one was the wristwatch, the middle one the cafeteria clock, the bottom one the central network. I shifted only the central network line to the right. Kang Taejun said nothing while I drew. Lines were better than a table. Anyone could see three people standing on the same road, with one of them speaking a single step late.

"O Sejin did not walk into the cafeteria after the broadcast sounded. The broadcast was late."

"He still walked into the cafeteria."

"Yes."

"And he did go to the reagent room."

"Yes."

"The gap between them is a blank."

Kang Taejun finished my sentence for me. The sentence he finished was more precise. A blank. Not a confirmed culprit, but space for a question to go.

I did not make a table. In front of Kang Taejun a table turns easily into a shield. Instead I set out only three scenes.

"Personal wristwatch 08:12:00, cafeteria wall clock 08:12:00, central broadcast silent. Broadcast 63 seconds later. Reproduced on Go Yura's test rig. O Sejin's reagent room door closed before the broadcast."

Kang Taejun took my words down. He wrote them one sentence at a time. Then he raised his head.

"And the access route for the data."

"Go Yura ran the test."

"The access route for O Sejin's alibi data."

I could not answer at once. Security office records were outside the range my clearance could open. What I had seen in an earlier loop and what I had checked without authorization in this one were mixed together. Kang Taejun does not miss that kind of mixing.

"Seo Ihyeon. You arrive at the right answer a little early every time."

"This time Go Yura reproduced it."

"Reproduction is a question of margin of error. The alibi data is a separate matter."

He closed the file. He laid a finger on the closed cover.

"Even with 63 seconds, you cannot confirm O Sejin as the culprit."

"I did not say confirm."

"Then why bring it to me first."

"Because I saw a loop where O Sejin dies."

Only after the words were out did I know I was too late. Kang Taejun set down his pen. His eyes went to my wrist. 4. O. Kang. Question mark. Ink I had not erased yet.

"A loop where O Sejin dies."

He traced my sentence back exactly as I had said it.

"In that loop the evidence would have vanished."

"Yes."

"So in this loop you suspect O Sejin first."

"It isn't suspicion. I checked an empty interval."

"Why does a man who checked an empty interval talk about a dead O Sejin first?"

I did not answer. Answer and I would have to say more about the loops. Say nothing and Kang Taejun suspects me more. Both were costs.

Kang Taejun locked the security office door. It was not full detention. Not yet. But the indicator inside the door turned from green to yellow.

"Wait here. I will confirm with Go Yura directly."

"What about O Sejin."

"The O Sejin you're worried about is alive. What I have to confirm right now is how you got that data first."

He started to leave and stopped.

"And, Seo Ihyeon."

"Yes."

"Correct for 63 seconds and a blank opens in O Sejin's timeline. At the same time, your own access times get recalculated."

The door closed.

In the security office glass, my face and the camera monitor behind me overlapped. Central time had just passed 11:00:00. My wristwatch already read 11:01:03.

A blank had opened in O Sejin's alibi.

A blank of the same size had opened in mine.
