Timezone in +/-HHMM format
Hey guys,
is thr any easy way of fetching Timezone of the Solaris server in (+/-)HHMM format using shell scripts. Say, if the current time zone is GMT, the script should return +0000 If the current timezone is Asia/Calcutta in /etc/TIMEZONE, the scripts has to return +0530

Straight shell does not do what you need. try perl:
Code:
#!/bin/ksh
get_tz()
{
perl -e '
use POSIX;
($sec, $min, $hour, $mday, $mon, $year, $wday, $yday, $isdst)=localtime(43200);
($sec1, $min1, $hour1, $mday, $mon, $year, $wday, $yday, $isdst)=gmtime(43200);
$diffmin=$min - $min1;
$diff=$hour - $hour1;
printf "%s%02d%02d\n", ($hour1 <= $hour)?"+":"-", abs($diff), abs($diffmin);
'
}
mytimezone=$( get_tz)
echo "my time zone is: $mytimezone"

You can reasonably expect a system to support POSIX specifications for the date command. POSIX does not specify a %z. That is a GNU extension. GNU date is a good program, but if he is on a multiuser system, getting GNU date installed may be neither practical nor allowed.
GNU date is clearly not what the OP is now using.
