Take into account timezone. Use millisecond precision. Maybe we could

nanosecond, but there were some float rounding concerns.
Alexander Strasser wrote an alternative approach to using timezone in
https://lists.ffmpeg.org/pipermail/ffmpeg-devel/2021-May/280179.html
yesterday.
And regarding the rounding concerns, we could maybe check for the
bitexact flag in avctx->flags and use it to either print
milli/nanoseconds or leave it as seconds.
Nevermind this part, this is lavf not lavc, and AVFormatContext bitexact
flag is not meant for demuxers, only muxers.
