Can someone please help me set the home city on my G-Shock 2310? On my other G-shock, the manual had clear instructions on how to do so, but the manual for this one doesnt. I tried searching in the existing threads but couldnt find this particular thread.

The easy thing to do would be to change in the timekeeping mode but that would screw up the timings in other time zones.

Any help on this would be appreciated.
