I think the sources you found are wrong, rather than game descriptions, whenever they talk or hint about a factor 10 for converting real time to game time. But we should test it. However they are right that 60 game seconds equal 1 game minute, and 60 game minutes equal 1 game hour. There are indeed 24 game hours in a game day, and always 30 game days in a game month. IIRC, weeks are called tendays like in pen and paper, so they last 10 game days. I don't quite remember if there are 10 or 12 game months in a game year though.

Anyway, to confirm the conversion factor of 12 is correct, I modified the Stoneskin spell so that it lasts 8 game hours and two rounds. I gave it a duration of 300 x 8 + 12 = 2412 real seconds. Then, with auto-pause active on spell cast, I used the spell and slept for 8 hours without interruption. Upon waking up, it took 12 real seconds for the spell to wear off.

That means 8 game hours equal 2400 seconds and 1 game hour is indeed 300 seconds, rather than 360: If it were 360, the spell should have wore off immediately upon waking up as it would have expired during the night, at the 6h42mn mark to be accurate.

The condition for this to be true is that a full sleep lasts 8 hours and not 6h40. But it appears from looking at both the game clock and the logs that the 8 hours condition should be met.

"many of the references I've seen indicate the game time is measured just as in real life: years, months, weeks, days, hours, minutes, and seconds so there should be 60 minutes (rounds) in an hour not 50?"

One round equals 72 game seconds, not 60. One turn equals 12 game minutes, not 10. It's always a factor 12, not 10. So there are indeed 60 game minutes in one game hour, since 5 turns equal one game hour :)
