converting decimal into time

[Anon]

Hi,
I am outputting the contents of a mysql database containing MP3's and need to add up the total time of all the tracks from any given result... Using

$totaltime = $totaltime+$time;

in the results loop gives me an output, but I need to convert this into time (ie. result = 16.96, when infact it needs to read 17.36 mm.ss)

Does anyone have a simple solution to this?

Thanks

mktime() can probably do that.
Otherwise it's too simple:
minutes = round(totalseconds / 60)
seconds = totalseconds - (minutes*60)
