[FIX] Timzeone Incorrect GMT Universal Fix (2.1/2.2)

---

This patch will fix GMT information for countries where GMT is set incorrectly. The fix can be applied to any HTC Android based phone from 1.5 to 2.2 ROMs. It may work for other vendors but I have only tested this on HTC devices.

I am located in Karachi, Pakistan GMT +5 but HTC Desire shows it as GMT +6. I emailed HTC about this issue last month and was expecting it to be fixed in Froyo release but sadly the GMT still displays incorrect GMT information.

This issue was too frustrating as I travel a lot and even if I manually set correct local time then the world clock will still show incorrect time for other locations.

I have created this patch which will fix the incorrect GMT problem.

Reboot into recovery and apply the patch

Note: Only for rooted devices

gmt-fix.zip will fix the timezone issue
gmt-restore.zip will restore the old timezone file

just tried this update on my non-rooted phone and it failed.

Got a error message "verification failed" Installation aborted.

It clearly says rooted devices only.

I had the same problem, showing status bar time as 5pm when it was 6pm, just to to time and date, change to 24h then back to 12h and its fine

this fix is for different issue where the Data/Time settings show incorrect GMT information for some countries.

if you try to solve it by setting manual time then world clock is messed up (as it calculates time of other regions by local time) and if you select different time zone by selecting some other country with correct GMT of your zone, then your home location and weather is messed up.

this fix changes the timezone files and show correct GMT. i believe the problem is caused for countries where Daylight Saving Time (DST) has been reverted but htc has hardcoded DST in settings. HTC should add a checkbox to enable/disable DST.

Thank you so much USB2007. I was waiting for this patch since ages. You have made my day

sorry but this patch didn't work for me.
installation was complete, no error
but the GMT is still one hour behind of what it should be

currently using latest radio, psychosis 1.2 LP rom.

1. Australia
2. the actual time is one hour ahead than the time shown
(london is set as GMT+1 somehow...)
3. rooted. running on froyo, psychosis 2.1 LP rom
link: http://forum.xda-developers.com/showthread.php?t=744879
4. installed through recovery, i am bad at adb...
installation was done after installing the rom (which means I did a full wipe before)
no error for the installation.


I just checked that sydney does have the GMT+10, which is correct. However, the time shown on phone is still one hour behind of what it should be
