[FFmpeg-user] Getting precise start time from wall-clock for capture

I'm using FFMPEG to record video from several cameras attached to several
networked computers. The computers' clocks are all synced. I'd like to be
able to get a precise date/time for the first captured frame; this will
allow me to easily sync the recordings later on. I've found that just
getting the date/time from the command line is not accurate enough--it
reflects the time that the file is first written to disk, but not the time
that the first frame is captured.
I found a similar question posted to StackOverflow (
and he describes the requirement quite well, though no one seemed to have a
workable solution (I tried the suggestions posted).
Anyone else have ideas for this?
Thanks very much!
