[gembud] GDATTIM error again

I am trying to make a graphic with topography and wave data from a wave
watch 3 model and my success at this has been on and off.  Most recently I
have encountered an error message due to GDATTIM:

[DG -7] Input grid TOPO ^150804/

I am not sure why the time is not properly being set in the gdtopo to make
the topograph.gem file.  Attached is the script (isolate3.csh).  Do you
know how to resolve this issue?

Thank you for your time,

Jason Snyder
