OK, so GRDLIST returns back the correct FDAY for FHOUR=6.
To get the same grid as I listed, you should run:
GRDLIST RTGRIDS/ETA.5 PAR=Z LEV=700 FHOUR=6 FORM=ALL GPRO=LAMB
I just pointed to your remote ADDE server and ran this command. Here is
what I got:

This is the same as what I got for grids filed on my machine (although
the position in the GRID file (the GRID column) is different. See
below for more details. The point is that the GRDLIST of data from
your file shows the same thing as a listing of data from my system.
The problem must, therefore, be in your GRDDISP.
When I run the following GRDDISP command while pointing at your machine:
GRDDISP RTGRIDS/ETA.5 NAV=F TDAY=CAL PAR=Z LEV=700 GPRO=LAMB FHOUR=6
the label is as expected:
G (GPM) 700 MB ETA RUN TIME 0Z 04 APR 2000 6 HR FCST VALID 04 APR/06Z
What do you get if you point at our machine:
DATALOC ADD RTGRIDS ADDE.UNIDATA.UCAR.EDU
EG B
MAP NA
GRDDISP RTGRIDS/ETA.5 NAV=F TDAY=CAL PAR=Z LEV=700 GPRO=LAMB FHOUR=6
Looking back through our FTP logs, I see that Lyndon State grabbed the
McIDAS-X 7.60 distribution on August 7, 1999. As far as I can tell, no
updates have been grabbed since then. I just looked through my Addenda
listings
(http://www.unidata.ucar.edu/packages/mcidas/mcx/addenda.html), but I
don't see a module modification that relates to GRDDISP, so I am
stumped as to why your system is plotting the incorrect forecast
day and time for the plot. Can I get a login to poke around?
>This is not the same as you got. It's grid 207?
On March 19, there was a change in the PDS Octet 6 values for ETA
grids. I include the text of this message at the end of this email.
The upshot of changing the Octet 6 values for ETA is that the Alaskan
Polar Stereographic grid 207 grids which had been marked for non-filing
by XCD in NOGRIB.CFG (should be in ~mcidas/workdata) are now allowed to
be filed. To turn off these grids, you should do the following:
<login to the machine running McIDAS-XCD (the machine running the LDM
to get the HRS feed is typically one in the same) as the user 'mcidas'>
cd workdata
decinfo.k SET DMGRID INACTIVE
edit NOGRIB.CFG and
change:
89 |-1 | -1 | -1 | -1 | 207| 207 | -1 | -1 | -1 | -1
to:
84 |-1 | -1 | -1 | -1 | 207| 207 | -1 | -1 | -1 | -1
This tells the McIDAS-XCD GRID data monitor, DMGRID, to NOT file grids
with PDS Octet 6 values of 84 on the 207 grid (Alaska Polar Stereographic).
In the next set of grid files that get decoded, you will not have the
207 grids in your ETA files.
decinfo.k SET DMGRID ACTIVE
Here is the announcement that went out to nws-changes:
NOUS40 KWBC 222027
