Ben, > To: address@hidden > From: Ben Howell <address@hidden> > Subject: Time Expressed in HHMMSS Format > Organization: SSEC > Keywords: 200311132000.hADK0FOb014376 units The above message contained the following: > Can you tell me what the appropriate "units" attribute is for time > expressed in hours-minutes-seconds? The numeric-value encoding format of HHMMSS is not a unit. Numeric values expressed in some unit form a mathematical group under addition. This is not the case for numeric values in such encoding formats. > Is this a time expression that does not conform to UNIDATA standards? It's a time expression that doesn't conform to the internationally agreed-upon definition of a unit. > Thanks! Regards, Steve Emmerson
