Yeah, local clock is UTC+1 and has literally no discrepancy to internet clocks (less than 1 minute).
I've just checked a few browser tabs with different hive threads I had opened at different times today. The issue only occurs for tabs that I haven't refreshed for some time and it goes away as soon as I refresh.
Old tab currently shows that you will post your clock question in 5 minutes, which would be 00:58 on my local clock.
Refreshed tab shows that you have posted
today at 8:08 PM, which is also weird, because it should be yesterday (assuming, day shift is at 00:00

).
Edit: Now properly displays
yesterday in front of your post (after my clock hit 01:00), i.e. day shift seems to happen at 0:00 UTC, even though I'm located at UTC+1 (Germany).
