NAME

Net::DNS::GuessTZ - guess the time zone of a host

VERSION

version 0.004

SYNOPSIS

  use Net::DNS::GuessTZ qw(tz_from_host);

  my $tz = tz_from_host('cr.yp.to');

DESCRIPTION

Brazenly stolen from Plagger::Plugin::Filter::GuessTimeZoneByDomain, this module makes an effort to guess an appropriate time zone for a given host. It will look up the location of the IP addresses owner and it will also consider the country code top-level domain, if the host is under one.

METHODS

tz_from_host

  my $tz_name = Net::DNS::GuessTZ->tz_from_host($hostname, %arg);

This routine returns a guess at the given host's time zone, or false if no guess can be made.

Valid arguments are:

  priority   - which method to give priority to: "cc" or "ip"; default: ip
  ip_country - whether to check the IP address's owner with IP::Country;
               defaults to true

Unlike the Plagger plugin, this routine will gladly make a guess when the country it finds has more than three time zones.

CAVEATS

This is fine if you don't really care too much about being correct. It's probably better than just always assuming local time.

Still, if possible, ask the user for his time zone when you can!
