#
# To Paul's list of time zone information on the web, I would add the
# following URL:
# <A HREF="http://www.dhl.com/dhl/dhlinfo/1bb.html">http://www.dhl.com/dhl/dhlinfo/1bb.html</A>
# or more simply:
# <A HREF="http://www.dhl.com/">http://www.dhl.com/</A>
#
# This is run by DHL (the courier company), and it presents a list of the
# countries served by that company. If you then click on a particular
# country, here's an example of what you'll see (graphics stripped out):
#
# United Kingdom
#
# HOLIDAYS: Jan 1, 2, Apr 14, 17, May 1, 29, Aug 28, Dec 25, 26
#
# INTERNATIONAL DIALING CODE: +44
#
# CURRENT LOCAL TIME: 09:41 Monday 6 November 1995
#
# I find this rather handy, and given that DHL covers 217 countries and
# territories, it's pretty comprehensive coverage.
#
# (I have no idea what system DHL is using to calculate the local time, but
# it's been accurate so far.)
