It is possible to customize the axis display so change it to display
timestamps in seconds on the major axis (with six decimal spaces) and
relative millisecond offsets on the minor axis.

This logic is unfortunately a bit dodgy. It looked like major label is
getting called before the minor ones, so I thought I could calculate the
relative offset for the minor for a more readable display. But after
scrolling and zooming around timelines some more I can see cases where
that doesn't seem to be the case.
Please have a play and if you think it is bad they only option will be
to absolute time for minor labels as well.
