Convert Epoch Time to Standard Date and Time & Vice Versa

Hi guys,

I know that this topic has been discuss numerous times, and I have search the net and this forum for it.

However, non able to address the problem I faced so far.

I am on Solaris Platform and unable to install additional packages like the GNU date and gawk to make use of their functions.

Hence, I intend to go for Perl and include a one-liner command in the shell script for the conversion.

As you can see below, I have no problem converting Epoch to Standard Date/Time.
But for converting Standard Date/Time to Epoch, I am not getting the correct Epoch value.

Am I missing anything here? Smilie

Convert Epoch to Standard Date/Time
Code:
bash-3.00# perl -e 'print scalar(localtime(1226424300)), "\n"'
Wed Nov 12 01:25:00 2008

Convert Standard Date/Time to Epoch
Code:
bash-3.00# perl -e 'use Time::Local; print timelocal(0,25,1,11,11,2008), "\n";'
1228929900
bash-3.00# perl -e 'use Time::Local; print timegm(0,25,1,11,11,2008), "\n";'
1228958700


Thanks in advance.
