Do you mean in stdout/stderr log output, or in stuff like vf_drawtext?
 If the latter, changes did land a few months ago to include
milliseconds in the vf_drawtext filter.  For the log output, you can
call av_log_set_callback() to provide a custom callback which includes
a more verbose date/time that includes millisecond resolution.  If you
want an example, I do it in my non-upstream tree here:
