Good question, but you know my answer would be biased ;-) As for local time
support, I don't really know of any libraries that do it really well.  IBM has
some timezone support as do the Roque Wave libraries.  Still I don't think
either use the TZ database or th Posix tz naming.  Bottom line here is I'm
hoping to raise the bar...

Yes, the plan is to read in from the csv file into memory.  User will control
the lifetime of the object.  For the whole world this will amount to a few
hundred entries in a map.  And of course you can edit down the csv file to
suit your needs.
