Internally SDP stores the date/time as Epoch time = the number of seconds elapsed since 1 Jan. 1970 00:00:00 UTC. The date/time displayed on the screen considers the time zone you have set up in your SDP preferences (personalize section). I am wondering what date/time is being considered when pressing the Now button in the calendar. Is it the time of your PC, the time of the SDP server (which may be in a different timezone) or the time as configured in the personalize options?
