[IDV #SYQ-598598]: IDV 2.7b2: GFS analyses and forecasts: faulty times

The docs in the catalog are wrong for this entry.  I've submitted a support 
request to the THREDDS group to have it updated.  Right now it reads:

NCEP GFS Model : AWIPS 228 (A) Grid. Global Lat/Lon grid. Model runs are made 
at 0, 6, 12, and 18Z, with forecasts hourly from 22 to 32 hours, then every 12 
hours from 192 to 384 hours (8 to 16 days). Horizontal= 73 by 144 points, 
resolution 2.5 degree, Lat/Lon projection. Vertical = 1000 to 100 hPa mandatory 
pressure levels (10 levels); surface, height above ground, pressure layers. 

At least the last part is right (192-384). ;-)

Bet on those futures!
