This function formats an elapsed time or a time-difference value by distributing the value in
seconds in to years, months, weeks, etc. (akin to using varying numbers of currency notes and coins
of different denominations for the same amount of money)
<?php
/*
* Formatted time-difference between $t1 and $t2 (seconds)
* The difference in seconds is distributed into years, months, etc. as specified by $format.
* $format is a string containing characters y, f, w, d, h, m or s, for years, months, weeks, days,
hours, minutes or seconds, resp.
* Output is an array containing keys y, f, etc., with the numerical values.
* Values are negative if $t1 is more than $t2.
