# *  This script displays the current date/time in any time zone and	* #
# *  compensates for daylight savings time.				* #
# *									* #
# *  Suggested usage:							* #
# *  <!--#include virtual="/cgi-bin/smcDate?zone"-->			* #
# *									* #
# *  Where:  'zone' is a one-digit time zone code as recognized by the	* #
# *          case statement below.					* #

# *  Determine the timezone to use.					* #
# *									* #
# *  I've tried to make it simple here by allowing a one character	* #
# *  argument. Based on that argument, I set the proper variable so	* #
# *  that daylight savings time is handled. For example, if I		* #
# *  indicate the letter 'P', the script will display the correct	* #
# *  Pacific time, whether daylight savings time is in effect or not.	* #
# *									* #
# *  Since I live in the United States, my code covers most of the	* #
# *  time zones used here. If there are other timezones that you need	* #
# *  to use, just add the corresponding code to the case statement	* #
# *  below. Or if you will always use only one time zone, then you	* #
# *  might find it beneficial to just remove the case statement 	* #
# *  completely and hard code it.					* #
