Help! Python to compare dates in diff. timezones

[Sunit Joshi]

Hello All

I have problem which is like this: 
I have two sites A & B which are in diff. countries in diff.
timezones.
Now both sites have same drawings (Microstation files with same names)
whose revision dates (as integer since epoch) are stored in a table in
database at both sites. The database structure is same on both sites
with identical table names.

Now since the sites are different timezones, I was wondering what
would be the best way to compare drawings, using Python, that have
changed between two sites; for e.g. if site A wants to gets a list of
all models that have changed at site A.

I'm open to any suggestion like using a query over HTTP, using XML,
etc.

thanks
