Just noticed that when you want to challenge another team you're (obviously) setting a time for the game.

I'm GMT +1, and believe I have set this up (somewhere) whilst registering.
Will users who are living in a different timezone get the correct timestamp for their zone automatically or are you meant to specify (i.e. time = gmt+1) when challenging?

I'm pretty sure they get the correct time as long as they have set the correct time on their user settings.
