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.
