Not sure about perl but in bash:

Code:
# epoch
$ date +%s

# If you have a time already in mind you can change the line above to use YOUR time and not system time like this:
Code:
date -d "Sat Feb  7 00:37:06 EST 2009" +%s

# result = 1233985026

# and back to regular time from epoch
Code:
date --date "Jan 1, 1970 00:00:00 +0000 + `date +%s` seconds"

#You can substitute `date +%s` in the line above with your own epoch time that you have already obtained

Code:
date --date "Jan 1, 1970 00:00:00 +0000 + 1233985026 seconds"

# result = Sat Feb 7 00:37:06 EST 2009
