One of the most wriggly cans of worms you will encounter as you bumble
through the labyrinth of IT nonsense.
You need a format that is non-ambiguous.
My fav is: dd-mmm-yyyy hh:mm:ss:hh
Of course there is the nasty, messy business of Time Zones to consider.
What paricular issue do you have atm?

Perl has no built in date formatting stuff, though the POSIX module
includes an interface to the strftime() system call. That uses the same
formatting as /usr/bin/date.
PHP has its own format. <a style='text-decoration: underline;' href="http://www.php.net/date" target="_blank">http://www.php.net/date</a>

Thanks for the php date info. What about the format for /user/bin/date? Any
similar table as on <a style='text-decoration: underline;' href="http://www.php.net/date" target="_blank">http://www.php.net/date</a>
I remember Apache web server's SSI has a date format for the
last-modified-date. Is that the same as php date or shell date?<!-- ~MESSAGE_AFTER~ --> >> Stay informed about: Date/Time Standred Formats |

Type "man date" at your command prompt, or Google for "man date".

I prefer the SI standard for the date, yyyy-mm-dd, as it sorts
correctly with standard tools.
