That's because the %z format specifier is not part of the ANSI/ISO
C89 Standard.  Each library implements %z as it sees fit.

I cannot reproduce this.  Your program works for me; here's the output

What version of DJGPP do you have installed?  Did you download, unzip,
and set up the djtzn203.zip archive?  Make sure you have your TZ
environment variable set to the file in the zoneinfo directory which
is appropriate for your time zone.  Also, make sure you have the
latest djtzn203.zip from SimTel.NET; the original v2.03 release had a
bug in the zoneinfo files.
