Measurement space¶

Time side (as recorded): the true time lies between -172800 s and -3600 s from the stamp: the delay range plus the interval one value describes.

Time¶

From UTC to the stored time stamp¶

Derived from this signal's timing table; a written chain is still to come.

The clock path first (UTC to the clock that stamps or spaces the samples), then the signal's own path to its stored time. Each bar: the time shift or error the step introduces (pale) and what is left after the atlas's correction (solid), on a log scale; dashed when estimated or assumed.

UTC

The reference every chain starts from.

Recorder PC clock

sync assumed 3 ms – 900 ms · clock link, parameter

Windows time synchronisation to the hospital's time server every 8–24 h (assumed), drifting a few ppm in between. Not observable in the release: dates are shifted to 2100. No step of 0.5 s or more was found.

Hospital records clock

transport estimated 60 min – 24 h

Delay from the end of the interval a value describes to its stamp.

Stored time stamp

window estimated 24 h

The width of the interval one value or sample stands for.

Timing¶

Against the working reference. Delay: from the end of the interval a value describes to its stamp. Interval: how wide that interval is.

Recovering the time of day	2026-10-12	current	The release shifts every case to start at 2100-01-01 00:00 UTC, removing the date and the time of day. The time of day (Korean local time) can be recovered to the minute from the admission date and the seconds of the EMR times.
