RE: Time Zone Computation

[Roger Harman <roger.harman@xxxxxxxxxxx>]

The data from iana.org was the closest thing I could find a few years ago.

My company has offices from Hawaii to New York but we just timestamp everything with local time of our Los Angeles office - PDT/PST.

I don't know of a public database of city, date, UTC offset. Because that's
what is needed for a generic solution to this problem. Because the date of
the switch between summer and winter time has changed through the years due
to legislation.

Perhaps a universal, generic solution is overkill for the immediate problem?
