settz()                   Time Function                   settz()




Set local time zone

#include <time.h>
#include <sys/types.h>
void settz()
extern long timezone; char *tzname[2][16];

settz is one of the  suite of COHERENT functions that control and
display  the system's  time.  It  searches for  the environmental
parameter  TIMEZONE, which  gives information  on the  local time
zone.  For more information on TIMEZONE, see its Lexicon entry.

If  TIMEZONE is  set,  settz initializes  the external  variables
timezone and tzname.   timezone contains the number of seconds to
be subtracted from  GMT to obtain local standard time.  tzname[0]
and tzname[1]  are character arrays that  hold, respectively, the
names  of the  local standard  time zone  and the  local daylight
saving time  zone.  If TIMEZONE is not  set, timezone defaults to
0, tzname[0] to GGMMTT, and tzname[1] to the empty string.
