#4495: date value "now" outputs "2036-02-06 06:28:16"

[http://ffmpeg.org/ffmpeg-utils.html#Date Docs] indicate that:
> If the value is "now" it takes the current (local) time.
However, at least with mp4 muxer, `creation_time` ends up as `2036-02-06
06:28:16`. Did not check for regression, or any other option that could
accept `now`.
