| That's because your time zone is not GMT0, but something else.  The range

zoneinfo was missing on my DJGPP machine.

| No.  You just need to make sure your TZ environment variable is set to
| your time zone.  See section 22.20 of the DJGPP FAQ list for more

Thanks.

I download djtzn203.zip from SimTel (by the way, this file name is missing in list of zip files).
Now my DJGPP machine contains zoneinfo with its subdirectories and files.
TZ=c:/djgpp/zoneinfo/israel

Here are a new run log file.

It seems that new log file is better than old one.
However, what happened to 1970 ?
