Youtube API v3 provides its video durations in this format "duration": "PT4M13S" Is this a standard time format? I'm trying to get a user friendly format using Objective-C. I would like to know if this is a Objective-C DateTime class supported format. If not what are those P,T, charactors stands for?

That is an ISO 8601 time format. PT indicates that we are dealing with a time peroid. H, M, S and similar ones are obviously the duration in hours, minutes and seconds, etc. I am not sure if Objective-C is able to handle this natively, but you may be able to find something useful knowing how it works.

this might help a bit, nevertheless this this an overkill, just to show video length.
