Description:

I looked at http://www.briandunning.com/cf/893, but wanted something to be using Timestamps, so either date or time i pass, it can format nicely... i think this is a nice generic function, and cos it uses Exact, u can add to it without worrying about substitution order etc...

To learn format options go to: http://uk3.php.net/manual/en/function.date.php

Timezone stuff don't work. If you wish to go the extra mile and get that working go for it and email me at tom "@t" seidler [dot] co_uk and i'll update this...

I've commented out the ordinal suffix option, cos it depends on another custom function, but kind of useful (http://www.briandunning.com/cf/118).

Note: these functions are not guaranteed or supported by BrianDunning.com. Please contact the individual developer with any questions or problems.

This is my Custom Function and I want to edit it

apologies to any who've used this so far, a few bugs, you know how it is with Mod(x - 1; divisor)+1 etc - i left em out in some places... notably the g and h, just corrected...

get in touch if u find any bugs...
