c - Linux, timezone and dst -

I am using RHEL 5.3 (linux 2.6.18)

I have a legacy code Which depends on ftime (3). Timezone and dstflag are not supported from me

now from the ftime (3) man page. gettimeofday (3) fields are not supported.

How can I get timezone and DST?

Thanks

You can tzset (3) :

  #define _XOPEN_SOURCE # & lt; Time.h> Include # include & lt; Stdio.h & gt; Int main (zero) {tzset (); Printf ("% ld,% d \ n", timezone, daylight); }  

Which of the "-3600, 1" prints on my system?

tzset also fills the array four * tzname [2] with the names of the standard and daylight saving time timezones names.
