time of day timestamps handling in gstreamer (v4l2 source)

Hi,
I have an existing application using v4l2 cameras on different computers
synchronized by ntp. The output (frames) of the different computers
are timestamped with the ntp time of the snapshot, provided by the v4l2
driver.
I can guarantee that the ntp time has no hickups (at least not when it matters).
I would like to rewrite this application using gstreamer. How can I
get the same quality timestamps at the output of my gstreamer pipeline ?
In other words : in which buffer attribute(s) can I retrieve that timestamp ?
Thanks in advance
Philippe
