[evlatests] Time error fixed.

[Vivek Dhawan]

The EVLA knickers have been untwisted. I heard that a re-synch of the L350
was done, followed by all the antennas. Ken (+ Hichem or Rob) may wish to
elaborate.

Here is a timeline, based on VLA online log entries (IAT/UT). I have verified
the first and last comments, the comments in between are by deduction.

UT date      startTime  project

2009-02-11	07:14	POINT    ! Known to be good.
2009-02-11	10:18	AB1321   ! Probably good.

2009-02-11	15:43	MAINT    ! Likely start of problem

2009-02-12	05:42	AB1321   ! First science affected.
                                  ! everything between affected.
2009-02-17	12:50	AW761    ! Last science affected.

2009-02-17	23:50   SOFTW    ! Problem fixed

I tested corrections I had derived earlier, by applying them to other data.
This did not go well. I suppose we can go ahead and contact the affected
observers, but it may take me a day or 2 to ensure I have a workable fix to
pass on to them.

Vivek.
