Time formatting from int (seconds)

Hi all, Quick question about the best (and easiest) way to format a display string into the HH:MM:SS format from an integer var. Is there a PHP function that will provide this? I've looked at the various functions and all are used for taking a date/time as use. Or is there a function someone has written and would like to share it? In my case I have the result of a subtraction of two date in which seconds are returned as in 980 seconds, 576 seconds etc. To make this readable to the user of the web page and so they do not need to mentally calculate the HHMMSS. Any ideas? Paul __________________________________ Do you Yahoo!? Yahoo! SiteBuilder - Free, easy-to-use web site design software http://sitebuilder.yahoo.com
