'Removing encoded date of mp4's metadata?

I want to remove encoded data in mp4 file for test.
for this, I try to use library like mp4box, ffmpeg, AtomicParsley.
But I can't.
How can I remove an encoded date in metadata?
Is it impossible?

Thanks LordNeckbeard. You're right.
it just the default value of mediainfo.
the real values is emptied.

I didn't look into it, but perhaps that's just the default value of what mediainfo displays if there is no creation_time metadata.

With MP4Box:

MP4Box.exe -time 0 -mtime 0 -keep-utc -add input.mp4 -new output.mp4
