This format was used by Steeveeo a while back, it would probably be a good idea if you were to use this for your hosting posts too.
Please make sure you give enough notice before a game.

A useful thing to use when posting your game. When posting time, use the following:
[url=http://www.timeanddate.com/worldclock/fixedtime.html?year=YYYY&month=MM&day=DD&hour=HH&min=MM&sec=SS]TIME[/url]
For example:
http://w ww.timeanddate.com/worldclock/fixedtime.html?year=2009&month=8&day=7&hour=19&min=0&sec=0
Note the time you enter is in GMT, so after making the link, follow it and see if it reports the corect time for your timezone. Adjust accordingly.
