This function is used to extract read-only date values from an Apple application's library. The following dates may be requested:
- Modification Date
- The date the track's metadata was last changed.
- Date Added
- The date the track was added to the application.
- Release Date
- The release date of the track. Typically this is only available for tracks purchased within the application.
- Played Date
- The date/time the track was last played.
- Skipped Date
- The date/time the track was last skipped.
If no value exists the destination track variable is cleared. If a value is extracted it is formatted as:
yyyy-mm-ddThh:mm:ss
The function only works on files which are linked.
