Sue, > Can a ut_unit be created from a string like the CF-1.0 compliant > units string: "seconds since 1970-01-01T00:00:00Z" ? Apparently not: ~/udunits2: bin/udunits2 udunits2: Character encoding not specified and not settable from environment variables LC_ALL, LC_CTYPE, or LANG. Assuming ASCII encoding. udunits2: Using default XML database You have: seconds since 1970-01-01T00:00:00Z udunits2: Don't recognize "seconds since 1970-01-01T00:00:00Z" It does accept "1970-01-01 00:00:00Z". Not accepting the string is a bug. Thanks for pointing it out. It'll be fixed in the production release.
