It comes from the GPS, which doesn't know anything about time zones or DST. You may be confusing it with the cellular network, which includes local time zone information. But GPS systems only know about Universal Time, essentially GMT. The head unit displays it according to the time zone you set and corrects for DST. The COMAND software was never reflashed for the recent change to longer DST.

you are probably right,i hate to admit it but i scrolled through the options using the steering wheel buttons and couldent find any way of manually changing the time,there must be a method but i didnt open the OM and read up on it.

You change your time from the system menu of your command. That time is automatically transmitted to you MFD.

The 2003 COMAND is an odd duck (widescreen but still CD-based). In the SYS menu under Date/Time, you select Country (Time), select your time zone and then you get the magic option to enable or disable automatic DST adjustment. The magic option is "Autom. S/W-Time." S/W doesn't mean "software." It means "summer/winter," the European term for daylight savings time.
If it's selected, COMAND will adjust your time according to what it thinks are the right dates. As you've seen, it is now wrong because we've changed DST since your COMAND was made. So disable the option, press the joystick button for 3 seconds to make the change take, and then go back to the Date/Time screen and change the hour. You're not allowed to change the time because it comes from the GPS, but you can make 30 minute changes which will work for time zone and DST changes. (Some time zones in India are x hours and 30 minutes from GMT, which is why one hour changes are not quite enough to cover all cases.)
As long as the Autom. S/W option is off, it's your responsibility to change the hour twice a year. Or you can leave it as it is and have your clock wrong a few weeks each year.
Simple, no?
