[GEMPAK #AJO-748565]: GEMPAK - Possible problem with 5.10 decoder

Steve,

I don't have old binaries for several reasons, including
storage space, the rapid change of the Linux environment making
old binaries obsolete, and old versions containing old bugs.

It sounds to me like you have a basic clock problem on your system, and/or
the file template and maxmimum number of times in a file is exceeding an
old file that is trying to be written to. The 4 hours is suspiciously
close to the EST/EDT + 1 hour in the future combination if that is the
time zone configured on your computer.

Ideally, the decoder action for metars uses -m 72 and a template
of YYYYMMDD for 72 hourly time bins in a daily file so that three 20 minute 
obsservation
bins per hour exist. If your clock/timedone is off or you are not using a time
template but instead are trying to use a set filename, you may be encountering 
problems with arriving at a 0Z to 4Z time for yesterday instead, or
a correct tiume, but your output file is already full of times rather
than containing the current days times.

Check your UTC and local time (date; date -u) to ensure you have correctly
configured your new machine. Then check your file template and maximum number of
times in the file. If you still have trouble, please provide me with your 
command line for dcmetr that you are attempting to use along with any log 
output.
It would help iuf you set the decoder verbose level to 4 for degugging
as well ( -v 4 ).
