[thredds] over written file has old global attributes

[Roy Mendelssohn]

Hi jean: '

My guess is you are getting the cached information, which hasn't been  
updated.  You can set the frequency of update in the catalog xml  
file.  Also, usually if you touch the file  (i.e. do something that  
causes to Thredds to access the data( that  usually also updates the  
info.
