World clock command line?

Is there a script to display simple world clocks (time in different places around the world) on the * nix terminal?

I was thinking of writing a quick Python script, but I have a feeling that I will work more than I think (for example, due to the configuration and output format) - not to mention rethinking the wheel ...

I have this bourne script shell:

#!/bin/sh

PT=`env TZ=US/Pacific date`
CT=`env TZ=US/Central date`
AT=`env TZ=Australia/Melbourne date`

echo "Santa Clara    $PT"
echo "Central        $CT"
echo "Melbourne      $AT"

I never thought about it, but it's not very hard to do.

#!/bin/sh
# Command-line world clock

: ${WORLDCLOCK_ZONES:=$HOME/etc/worldclock.zones}
: ${WORLDCLOCK_FORMAT:='+%Y-%m-%d %H:%M:%S %Z'}

while read zone
do echo $zone '!' $(TZ=$zone date "$WORLDCLOCK_FORMAT")
done < $WORLDCLOCK_ZONES |
awk -F '!' '{ printf "%-20s  %s\n", $1, $2;}'

Given the input file:

US/Pacific
Europe/London
Europe/Paris
Asia/Kolkatta
Africa/Johannesburg
Asia/Tokyo
Asia/Shanghai

I got the result:

US/Pacific             2008-12-15 15:58:57 PST
Europe/London          2008-12-15 23:58:57 GMT
Europe/Paris           2008-12-16 00:58:57 CET
Asia/Kolkatta          2008-12-15 23:58:57 GMT
Africa/Johannesburg    2008-12-16 01:58:57 SAST
Asia/Tokyo             2008-12-16 08:58:57 JST
Asia/Shanghai          2008-12-16 07:58:57 CST

I was fortunate that it took less than a second to run and did not cross the 1 second border.
