Re: [CF-metadata] generalizing forecast_reference_time and forecast_period

2011-05-18 Thread Schultz, Martin
Dear all, once again I haven't followed the entire discussion carefully, but I sense there is more to the problem than what has been discussed so far: 1) if we define the meaning of "time" as a specific datetime instance on a given calendar, then all time values along a trajectory should in

Karl (also verified by Rich) - thanks for the replies. I was using the previous release of the cf-checker which throws errors rather than ignoring and/or reporting as "info". Thanks!! Chris From: Karl Taylor mailto:taylo...@llnl.gov>> Date: Wed, 18 May 2011 15:21:18 -0400 To: "cf-metadata@cgd
