I will digg into the date thing a bit better and see what can be done.
Anyway I think this might be a ncBrowse issue.
In my case I used the time format:
milliseconds from 1970-01-01 00:00:00 UTC
while I note that usually the used format is:
hours from 1970-01-01 00:00:00 UTC

Regarding the CRS format, I think we will not get out of this
successfull. The geotools and netcdf libraries really deal in a
different way with the formats and not all the same crs are supported.
So I really think that the lat/long choice is the best. I also is done
like that in the ncWMS project, which uses netcdf for reading and
geotools for rendering  the WMS map. In that case data are always read
in whatever projection and first reprojected to 4326. Then things are
projected back to whatever the user asked for. Not so nice, but it is
the interface point between the two libs I guess. Will try to ask some
expert about that.
