Nokia 6600 Call Log time

Hi guys
I got a nokia 6600. I live in India and recently noticed that when i set my Clock to auto update or manually to GMT Offset +05:30 the calls i make or are missed do not display the proper time. For eg. If a call is made or missed or received at 2:00 Pm it shows 1:30 Pm in the log. The Clock is set to the perfect time by me always no matter if it is on auto update or manuall settings. Once I shift the auto update off and set the GMT Offset to 00:00 the time in my log is displayed properly.Could someone help me out please

This problem is there with the 3650 and the 7650 also. This problem starts only when the phone is connected to the pc the pc suite automatically sync the phone time with the pc.

To solve this problem just change the computer's time zone to 30 mins before or after the time zone that currently set in the system and connects the phone for sync. Now the time will be logged correctly.

P.S For how much did u get the 6600 for and from where?

No that did not help either it has got to do somehting with the phone itself the time that it displays is the current time but log's 30 mins less in the calls it makes or misses i really dont know what to do have been working on it the whole day
I got my phone from Dubai (UAE) for about $475 with a 5 yr international warranty
