[webservices] irisFetch.Traces returning duplicate values for unique SNCL-time

Hi Mary,
You've found a gap in the data that is to big to be automatically bridged.

Here...
>> datestr([primary.startTime])

ans =

06-Feb-2013 01:12:35
06-Feb-2013 02:22:21

>> datestr([primary.endTime])

ans =

06-Feb-2013 02:15:40
06-Feb-2013 03:12:34

So, it looks like there's a huge gap between 02:15:40 and 02:22:21 

Because there was no data there, irisFetch doesn't know how to connect the two, so it gives you two traces instead.

This is likely a condition you'll have to keep an eye out for in your processing codes; as I bet it has other implications for processing.

Cheers,
Celso
