Certainly looks strange and I can't recall any such bug.  (Time scales are a bit dodgy right now and won't get a thorough examination until after 4.0... doesn't rule out small bug fixes.)

Could you make this easier for other to reproduce by showing the plot command and perhaps pull just a few sample points from your file?  E.g.,

plot "-" with ...
12:00:00 5
12:29:29 10
12:59:59 5
end

(I'm not real familiar with the time syntax.)
