Hi Patrick:
So WMS datetimes are probably being done through ncWms, using Joda Time
library, whereas the TDS opendap service will not interpret the dates,
so it must be the ferret client, presumably using udunits C library.
Its hard to imagine 2 date libraries getting different answers, but
since one is done on the server, and the other on the client, it must be
the difference in the gravitational attraction of the moon between the
two locations, causing a slight difference in the length of the month.
Do you by any chance know what is the correct answer?

Hi all,
I have a strange behaviour with time dimension values exposed by the
GetCapabilities
and values get from an OPeNDAP access.
Could someone explain me what is the source of the problem ?
