Some people capture using equipment that provides nanosecond timestamps. I
don't think it's a good idea to throw away digits in that case. The GTK+ UI
always uses 9 digit precision for the start time and 4 digits for the duration.
Change 17448 updates the Qt UI to use 9 digit precision for the start time and
6 digits if the capture file has nanosecond timestamps, and 6 digits + 4 digits
otherwise.

Note that a different change (17396) adds a visual timeline graph to the start
time and duration columns. This gives you fuzzy and detailed conversation times
in the same place.
