It does provide subsecond precision, please see the 'millisec' variable
here:

Adding the ability to print time zone information is a good idea, I think.

The patchset allows to control whether to print date, time or both.
In practical use, I ended up printing a line with the date on startup
and print only time information, e.g. like this:

01:40:42.467 ffmpeg version 5.1...
01:40:42.467   built with ...
01:40:42.468 Execution Date: 2022-08-16 01:40:42
01:40:42.499 Input #0, matroska,webm, ...



If there is interest, I can submit my latest version of this.

Best,
