A KSH or Perl script is hardly portable in that sense, though it's potentially easier to install Perl or a recent KSH than GNU date.

Date math/conversion/formatting, I think, remains a pretty big pothole.

Korn shell (ksh) usually comes in a 1988 or a 1993 version.

AFAIK Solaris has a ksh93 available.

I hope this helps.

if you want to use Perl for predefined date you can use below code:-

Code:
#!/usr/bin/perl -l

use Date::Parse;
print str2time("Mon Apr 18 16:45:00 UTC 2011"); #1303145100
print str2time("04/18/2011 07:45:00PM"); #1303145100
print str2time("2011-04-18 19:45:00") ; ##local time zone is Asia/Amman which is GMT+3 #1303145100
print str2time("2011-04-18 16:45:00 UTC") ; #1303145100
print str2time("2011-04-18 16:45:00 GMT") ; #1303145100
print str2time("2011-04-19 01:45:00 JST") ; #1303145100

Note:- JST time is Japan standard time (UTC/GMT+9), and UTC is same as GMT time.

I typed a cntl-V after the "set -o emacs" to get the version info.
