I had the same issue in my first game from changing the speed of the game at one point my fire had 139 hours left of burning time. To fix this all I did was exit the game with it still running don't pause it and reopened and all of the timers were correct after that. I hope that helps.

Before I did as you suggested:
At 23:03 my Pg female time changed to 102 min.
The 13 year old is at L O N G last 14.
I'll be darned, I did exactly as you suggested and nothing changed. I then repeated your suggestion and waited for about 5 min; ..and grateful me, my time is back to normal.
Thanks very much!
Tuesday morning at 01:40 hours, my Pg female gave birth to an adorable female redhead, named "Zania."
Thanks all!
