Hi John,
Thanks, testing that now! And wow, that's not fixed in the NCEP GEMPAK
version, which explains why NCEP is having troubles tonight!
SYSTEMS STATUS...
NCO dataflow and software development support have been working
the issue with loading surface/upper air and lightning obs, and
WWA plots in NAWIPS. The problem appears to have been traced to
an LDM issue. We are attempting a fix to hard code the year until
we can engage UNIDATA support.

I also believe that fl/flmnam.f needs fixed. That is what solved my demetr
issues.

Hi Kevin and others,
I suspect there are more changes needed. Diffing Unidata's GEMPAK against
NCEP's GEMPAK for the gemlib/ti/ folder and removing the timezone changes.

Looks like $GEMPAK/source/gemlib/ti/tiyy24.f is the file that needs to be
changed.

Hi, Pete,
This is the result of a GEMPAK bug within the time library. The version of
GEMPAK you are using does not recognize the year 2021, rather it reverts back
to 1921. So, instead of a Y2K bug, it's a Y2K21 bug.
The internal NCEP version of GEMPAK had a patch released earlier in December to
address this bug, but I suspect no one has incorporated this patch into the
community version.

Greetings. We are experiencing an unusual problem. NMAP2’s (v 7.1.1) data
selection window can’t seem to detect grid files for fhrs valid past Dec 31
2020.
This is happening with all our model grid data no matter if it’s the gfs,
ecmwf, naefs, gefs, etc. and for what its worth, the restore files do NOT have
a fhr limit specified.
Quick example is a listing of today’s 00z ECMWF which is typical and contains
the basic 500, 850 and surface fields out to f240 and which we can plot just
fine using gdplot3

However the data selection window in NMAP2 only shows data through fhr 120. At
the time of this writing fhr 120 corresponds to Dec 31 2020 00z.
By tomorrow we will only be able to see in NMAP2 data out through fhr 96 and so
on.
We did try to mess with the Calendar function but this did not help. If anyone
else is experiencing this and if so any workarounds?
