Changing TZ from a script
Hi i have a case statement so when the user selects a differnent timezone the TZ value should change, so when another script generates a html page the when date is displayed the time corresponds to the timezone selected. I can't get the TZ to change when using a script but can change the TZ by inputting the code in the terminal:

Code:
echo "Timezone - Choose a Zone - GMT, Asia. "
read Time
case "$Time" in
	GMT)
	unset TZ 
	;;
	Asia)
	echo Time="export TZ='Asia/Kolkata'" >> config.sh
	;;
	*)
	echo "Unknown Time Zone" 
	;;
esac
done

is this possible or what would be an alternative solution for the user to select a timezone from a case statement and change the time displayed via the date command?

thanks

tzselect

TZSELECT(1)                                                Debian Timezone Configuration                                               TZSELECT(1)

NAME

       tzselect - view timezones

SYNOPSIS

       tzselect

DESCRIPTION

       This  manual  page  explains how you can use the tzselect utility to view the installed timezone. It comes handy when you want to know what
       time it is in other countries, or if you just wonder what timezones exist.

       tzselect is called without any parameters from the shell. It shows a list of about one dozen geographic areas one can roughly recognize  as
       continents. After choosing a geographic area by number, a list of countries and cities in this area will be shown.

       You  can  press  the  Enter key to reprint the list. To choose a timezone, just press the number left to it.  If your input is invalid, the
       list will be reprinted.

       You may press Ctrl-C to interrupt the script at any time.

       Note that tzselect will not actually change the timezone for you. Use 'dpkg-reconfigure tzdata' to achieve this.
