[evlatests] EVLA Time error fixed.

[Vivek Dhawan]

Please discard earlier message, it had a line out of sequence.
This is frying my brain!

| The good news:  Its still fixed.
|
| The other news: It did not break when we originally thought,
|                  but later With No Apparent Provocation.
|
|                  It broke twice on Feb 14th, by differing amounts,
|                  again WNAP.
|
|                  It fixed itself WNAP, before we 'fixed' it again
|                  by re-synch. It has stayed fixed since Feb 18.
|
| A revised timeline is below (times approx).
|
| The only science project I can find that might be affected is
| Urvashi's. Its hard to tell because of the frequency switching.
| Since she can apply self-cal to M87, and the time offset is
| smaller than the integration time of 5s, even a wide field
| should be immune after self-cal.
