I know that at least one contest refers to "Forum Time" for an entry deadline. The time that displays at the bottom of every page is the member's local time calculated from the server clock, presuming that he has his time zone set properly in his profile.
So it might be a good idea to either note a specific time zone when referring to forum time, or to use GMT.
