[IDV #UUL-161546]: Re: 20150504: Support Request from IDV 4/27/15

Rebecca,

I spent quite a bit of time looking into this problem this AM, and I believe we
have a bonafide IDV bug which I have not gotten to the bottom of yet.

But can we step back a moment and talk about your ultimate objective? The truth
is that the IDV is not really designed to be a data conversion tool.  If data
conversion into Excel is solely your ultimate objective, there may be better
ways of going about about this problem.

Also, I don't believe your date range has simply been shifted. But rather the
dates are actually corrupt. Simply export the first time stamp and you will see
that it gets shifted from the original January back into December.

Best,

Unidata IDV Support
