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

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? ____
