Re: [thredds] Problem between OPeNDAP and TDS when netCDF file is modified

Hi John:

A question my group has wondered about is TDS suppose to be looking at and 
storing last modified times of files?    If  that is not in the code presently, 
that could explain a lot.  If it is the intent in the code, then may I strongly 
suggest that is not happening properly.  We have a lot of reason to believe 
that is the case.
