Summary0013843: netCDF CF reader should be more lenient on time units.
DescriptionIn order to specify a dimension as time within the netCDF CF reader, there must be a dimension variable with a units properties containing a string of a known time unit (as per the CF specification). However, that check is currently only looking for the substrings " since " or " until " expecting the units to be in the form of "<time_unit> since <date>" or "<time_unit> until <date>". However, the reader should also accept strings that match a valid <time_unit>.

The CF convention defines units as anything accepted by the udunits package ( [^]). The attached udunits.dat (a text file) should contain a complete list of all time units that should be supported.

Trusting Ken, since I don't know how to test this fix. The attached file is not a netcdf file, but rather an information file.
