I have followed the instructions given on this site earlier and they work except for the date. It remains at the original year of 1985. Here are the instructions given (which don't work for the year)
1. Press and hold all three buttons for two seconds to reset the clock after changing batteries or things are messed up.
2. Press the time zone on the front that you want to set the time to. Use standard time to start.
3. Press the A button to page through seconds - minutes - hours - day- month - year - 12/24 mode.
4. B button on most advances the units by one; holding on seconds it holds it at zero for hacking.
5. Day of week is correct if day - month -year is correct.
6. C returns clock to run mode after setting.
7. Press zone to see time in that zone, then press DST is in effect.
