incorrect time return in GetObservation

[Jim Potemra]

I now have oostethys up and running (http://oos.soest.hawaii.edu/
oostethys), and the configuration seems to pass the test. However,
both GetCapabilities and GetObservation return incorrect times. The
input files are netCDF, pass the CF-1.4 compliance test, and should
start on Jul 1, 2008. I pad the files to have missing data through
the end of 2010. Both GetCapabilities and GetObservation return start
dates of Jan 1 2011:

http://oos.soest.hawaii.edu/oostethys/sos?VERSION=1.0.0&SERVICE=SOS&REQUEST=GetCapabilities

returns:

<sos:time>
<gml:TimePeriod gml:id="timePeriod6">
<gml:beginPosition>2011-01-01T17:20:00Z</gml:beginPosition>
<gml:endPosition>2011-01-01T23:56:00Z</gml:endPosition>
</gml:TimePeriod>
</sos:time>

Same file via THREDDS:
