modis-001 / 1.0.0 [M1]: The server advertises
temporalDomain.timePosition 2002-001 but GetCoverages fails with
'msWCSGetCoverage(): WCS server error. Underlying layer is not tiled,
unable to do temporal subsetting.' if TIME=2002-001 is used. The same
with GDAL and gvSIG. This is well known problem which I have already
reported in mapserver list.

Other layers work with WCS 1.0.0, also with GDAL and
gvSIG-1_11-1305-final (it is using 1.0.0 by default).

OTOH, modis-001 is the only one working correctly with WCS 1.1.1.
Other layers have all pixels 0. The same with GDAL.
