(Recording some notes here for myself to investigate later - this was reported over bmail and I wasn't able to quickly figure out what was going on.)
Apparently the global played time has been stuck at a specific value ("5147 years, 35 days, 3 hours, 14 minutes, 7 seconds") for at least a couple months. The "per day" value has been steadily decreasing:
- 2021-11-22: 15 years, 130 days, 2 minutes per day
- 2021-11-25: 4 years, 8 days, 11 hours, 21 minutes, 54 seconds per day
- 2022-01-26: 1 year, 98 days, 15 hours, 53 minutes, 36 seconds per day
No obvious explanations: Played time for individual bots seems to be increasing as expected. Nothing special about the global number of seconds played (somewhere between 2^37 and 2^38 seconds). The data looks okay AFAICT, so I'm guessing something wrong is happening in the PHP layer.
