brancusi has asked for the wisdom of the Perl Monks concerning the following question:

This must be so simple that I'm overlooking the obvious, and can't believe this hasn't been done on CPAN - but I'm not finding it :( I have an Olsen style timezone of the form "America/New_York" returned by the Geo::IP module and I also know the UTC from my server. How do I convert the UTC into the local time of the person viewing my website given all I have for offset information is the long Olsen type timezone? i.e. how do I convert the Olsen timezone into a NUMERIC offset? TIA Brancusi

    use DateTime: 
    # assuming your server's localtime is in UTC
my $local = DateTime->now->set_time_zone( $olson_name );

    Date::Manip has functions for doing just about anything with time.
