I was out this week, but thanks to Tom for figuring this out.
Because this issue has come up before, I just wanted to comment
on one thing.
CF checkers only seem to check some of the CF compatibility. Just
because it passes the checker, it does not mean that the file
adhere's completely to the CF convention. I'm not sure what it
checks, but it doesn't check everything. We've had others who
report their files pass the checker, but in reality, there are missing
attributes that are necessary for true CF compatibility.
I will look into the unit parsing for this case though. I'm
pretty sure that the underlying VisAD unit parsing only handles
UTC, GMT and Z as valid timezones. I'll see if we can ammend that.

I have a netcdf file that the CF convention checker
(http://titania.badc.rl.ac.uk/cgi-bin/cf-checker.pl) likes. IDV is
supposed to like CF data, even the 2 D grid data like my file. I have
included the first few lines of my cdl file from ncdump and am wondering
if anyone could give me a few pointers on how to correct the file for
IDV compatibility.
Thanks in advance.
