This also causes errors with gdalwarp and when combined with other datasets (with [-180,180] values), they are not aligned properly due to a 180 degree longitude shift. Simple fix is to test for longitude variables (using CF metadata explained in CF sections 4.1 and 4.2) and convert any values in the [180,360] interval ti [-180,180] by subtracting 180 - in IReadBlock and also in SRS detection. It would be better to address this in GDAL or PROJ, but this fix is much simpler and less involved.
