Oops, didn't notice this because it was in a different thread. Well now
you have two Perl solutions :)

You can do it very easily with perl:
#!/usr/bin/perl -w
use POSIX (strftime);
($d = strftime("%z", localtime)) =~ s/(\d\d)(\d\d)/$1:$2/;
print "$d\n";
but it's probably a bit too heavyweight to use perl to format the
string if you aren't already writing a whole script in perl. Instead,
try:
date +%z | sed -e 's,\([0-9][0-9]\)\([0-9][0-9]\),\1:\2,'

RE: timezone command
Yes that is close enough for an starting point, thank you.
I need $timezone to hold the time zone in this format -00:00
The command date +%z will give it as -
I know nothing about writing perl scripts.
Can somebody show me how to add the : in the output
of the date command in the simple following script?
The cat statement is just so I can see results are correct.
#!/usr/bin/perl
$timezone=date +%z;
cat $timezone

Try 'date +%z' to get the timezone in the format "+0200".
Not exactly what you asked for, but almost.

RE: timezone command
I know how to set timezone, date and time.
I am looking for command to display on the console screen the
systems timezone in this kind of format "-00:00"
Is there such an command or some way to get this info?
In an perl script I tried $timezone= $ENV{TZ} and I did not get
00:00 format which I was looking for.

Not quite like that (are you in Pakistan?). The problem is that
time
zones aren't that simple: they contain information about daylight
savings time, as well as implicit historical information that gets
lost when you reduce it to a number. Admittedly, Pakistan doesn't
seem to have DST, but that's the way it is.
In general, the system time zone is stored in the file
/etc/localtime.
You can set it with:
# cp /usr/share/zoneinfo/Asia/Karachi /etc/localtime
# date
Fri Apr 16 08:55:27 PKT 2004
If you remove it, it defaults to "GMT" (really UTC):
# rm /etc/localtime
# date
Fri Apr 16 03:55:37 GMT 2004
Even then, you can specify the time zone explicitly with the TZ
environment variable:
# TZ=Asia/Karachi date
Fri Apr 16 08:55:45 PKT 2004
