I am writing perl scripts for nagios. I am getting a value $time_new from a subroutine. I am using 
$time = `date -d '$time_new' '+%s'`;

[download]

to get the number of seconds from epoch (for e.g. date -d 'Tue Feb 13 19:04:04 IST 2007' +%s, gives you 1171373644). It is running fine on Linux, when I run my script on SunOS Unix, the script fails.
I checked with man pages of SunOS and found that there is NO +%s option in Unix date command.
Any suggestions please
