Converting Raw Seconds to 00:00:00 format

[hellrider]

I have an NSTimer that spits out a float value every 1/16th of a second. (Every 1/16th of a second, 1/16 of a second is taken off the float value).

The application functions as a countdown timer, so I want the raw fractional seconds (i.e. 9.9375) to be converted into (hours:minutes:seconds:000).

This is somewhat hard to explain, and I apologize, but right now, I have an NSString that looks like 9.xxxx; my goal is for it to look like 00:00:9xx.

If this is possible, I would appreciate some guidance.

Thanks.

I would suggest using NSDateFormatter after creating an NSDate using method dateWithTimeIntervalSinceReferenceDate:
