That does seem like bad documentation, indeed. The UDUNITS packages won't recognize the unit "date". You have to realize, however, that the stand-alone UDUNITS packages were created independent of the netCDF packages (let alone the CF conventions). I also don't interact with the CF folks all that much. Having written that, I do know the netCDF developers quite well (the CF conventioners not so much). I'll bring this to their attention immediately. Hopefully, you'll hear from them soon. > -Rob > > Thanks, > Rob > ------------------------------------ > Rob Raskin > Group Supervisor, Science Data Engineering and Archiving > Instrument Software and Science Data Systems Section > Jet Propulsion Laboratory > Pasadena, CA 91109 > (818) 354-4228 Regards, Steve Emmerson Ticket Details =================== Ticket ID: EYN-795297 Department: Support UDUNITS Priority: Normal Status: Closed
