nts to MtkPixelTime() to actually compute the
pixel time at a given SOM X/Y location. It should be noted that the
pixel time metadata is only available in MISR L1B2 Ellipsoid product files
and not L2 product files. However, one can read the time metadata from
a L1B2 Ellipsoid file and easily compute the pixel date/time of any
SOM X/Y location at any resolution of another data product as long as
the path and orbit are the same.  The pixel time actually varies according
to camera by approximately 7 minutes. T
