How awkward is it for you to read 24h time stamps?
I grew up in a culture where we say "two o'clock" in the evening hours, but all digital clocks display "14:00". I only know the AM/PM dance from school textbooks and the Internet.
So ISO date-time stamps with 24h-formatted hours came natural to me: 2020-05-19 15:03, which is easy to shorten into 202005191503.

I was thinking about this when Sascha mentioned something about encoding the IDs with a different base than 10, and noticed how neatly date-time IDs increment strictly monotonic. The first 4 digits are for the year. (The year 9999 would be
7pr in base36). The second 4 digits are month and day, and that combination always increments monotonic as well, but with gaps (after 0131 aka Jan 31st comes 0201 aka Feb 01st). The largest number possible in that chunk is 1231 (
y7 in base36). And the last 4 digits for the time increments, too, in 24-hour-format. (23:59, the largest value, is
1tj in base36) 12-hour-formatted timed would repeat and need a AM/PM flag that can make the number non-monotonic if you append the flag to the time (say
1 as a suffix, e.g.
12000 for AM,
12001 for PM, would not form a monotonic function values.
Edit: Ah well, this also applies to the whole number 🙄 So the monotonic property of the 24h format is given even then.
Edit 2: I came to this sudden realization due to/after ridicule by @sfast 😛
