a sequel to my Current Age Script, now it supports up to the last minute. The new catch though, is it only supports times after the unix epoch, because the main function im using here is strtotime(). But there is a workaround to this though, you can avoid using strtotime by specifying the month, day, year, hour and minute in the variables.

This could well be used in forums, for tracking how long the user has been away, or how old the post is, and stuff like that. Hope you enjoy.

P.S.

The class.grammar.php is just a grammar library I wrote which is responsible for concatenating the letters 's' to the words 'month', 'day', etc.. if the number is greater than one. It should be available on the archive.
