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
millisecond offsets on the minor axis.
v2:
* Give up on broken relative timestamps.

I'm still seeing some kind of strange offset. However, it appears to be
browser dependent. If I use Chrome then the offset is +28.8 seconds.
With Firefox it is -59958115.2 seconds! On the other hand, if I try Edge
or IE then I don't get a graph at all. I'm wondering if the issue is
with Vis browser compatibility rather than anything in the trace.pl
script. Are you seeing anything at all similar?
Hmm, if I comment out the 'format:' line and go back to the unformatted
time stamps then IE & Edge still show nothing. However, Firefox shows
dates based on a year of 0097 whereas Chrome says 1997.
Either way, I can't spot anything in this patch that could cause a
random offset. So...
Yeah, I can see that now that I tried in Firefox. I was using Chromium
so far and there timestamps are exactly matching the ones from the
tracepoint log. Which is what we want for easy correlation between the
log and HTML..
Firefox corrupts that somehow by applying the large negative offset to
everyhting. Perhaps around two year worth of negative seconds if my
rough calculation can be trusted. Or Vis under Firefox, I wouldn't know
really who is to blame.
I have no idea what to do here. :(
