 Summary of the bug:
 When creating a mov from a mov ffmpeg carries forward the "creation_time"
 metadata from the original file (if it exists) such that the reported
 metadata (fprobe) is incorrect for the file that it has just created.

 How to reproduce:

 Notice from the above how the output creation_time is the same as the
 input times.. "creation_time   : 2012-06-08 06:31:48"
