Timestamps in AVPlayer

I want to show the user actual start and end dates of the video played on the AVPlayer time slider, instead of the video duration data.

I would like to show something like this: 09:00:00 ... 12:00:00 (which indicates that the video started at 09:00:00 CET and ended at 12:00:00 CET), instead of: 00:00:00 ... 02:59:59.

I would appreciate any pointers to this direction.

As an additional background, I use a m3u8 file, which contains the following metadata.
