The BIOS offers basic clock functionality that can be customized by the user. This allows programs running on the Mark 1 to determine the time and date set by the user instead of relying on LSL time and date functions. The clock automatically synchronizes with SLT (either PST or PDT) as sent by the server, but the time zone and DST can be changed by the user.
