#653 one day of data ends up displaying two

[Jeremy Faden]

If I try to plot:
vap+dat:http://user:pass@mapsview.engin.umich.edu/data/MAG/KSM/MAG__KSM__$Y$j_0.TAB?depend0=field0&bundle=field2-field4&timerange=2003+July+16

I end up getting a two-day plot. I've seen this sort of problem before, but not for a while. This is in the autoplot2010 branch.
