Just brought my MBP home the other day. Noticed that the clock on the menu bar wasn't right so I went into "open date and time" and set the time zone - which was on GMT. This set the analog clock visible under the "date and time" tab to the correct time. However, the digital time above it was five hours ahead. So I unclicked "set date and time automatically" and reset the digital clock. Unfortunately the analog clock moved too, setting it now five hours behind. I played around with it for awhile but could not get the two clocks to sync. If I re-click the "set date and time automatically" the digitial clock goes back to five hours ahead (and the analog clock displays the correct time). Also when I re-open the date and time window the time zone has always reverted to GMT.
Any ideas what's going on here - and how to fix it?
