Customise DST Rules?

[Guest SDMR]

I live in Pakistan. There are no fixed rules for daylight saving time here, but we are currently GMT + 6. Android (and every other OS under the sun) does not know this and insists that Pakistan is GMT + 5.

In short, can anyone suggest a way to edit the DST rules in Android so that I can display the correct time?

The two obvious workarounds (changing the base date/time setting to be GMT + 1 or changing my current timezone to be GMT + 6) both have disadvantages and cause problems with e.g. Amazon AWS requests and Home Screen widgets which display time and weather.

Any suggestions gratefully received. And, if it is relevant, I am running Paul's latest ROM (rooted etc.).
