AbigailII: Fischer clock settings means no vacation days on this site. So I'll assume it's not a Fischer clock game
The fact that you already spend your vacation day is not a problem - it's set on your account as a vacation day. Any other game that would otherwise timeout during that day will also get extended time when the moment arrives without wasting another vacation day, this is already how it works today.

nodnarbo: After a site's downtime no time checking functions are running on the site, if I understand correctly. That's why games go into negative time - there's no function running that will make them timeout in the background. However, if you allow games to go into negative times in normal conditions (while all these processes are executing) changes could indeed be profound.


Again, my main point was that NO CHANGES in the timeout or vacation days mechanisms need to be done. The only change would be the calculation of the deadline for timeout. Everything else would continue to work as currently. But, of course, only Fencer can say for sure if my reasoning is correct or not - he's the master of all time around here
