tzset 

Sets time zone conversion information.

Syntax 

     #include <time.h> /* proto */
     void tzset (void);

Parameters 

None.

Return Values 

None.

Description 

The tzset function uses the value of the user-defined environment
variable TZ to set time conversion information used by localtime(),
ctime(), strftime(), and mktime().

The tzset() function sets the external variable tzname:

     extern char *tzname[2] = {"std", "dst"};

where std and dst are described in the HP C/iX Library Reference Manual.
If no TZ environment variable exists, Eastern Standard Time (EST) and
Eastern Daylight Time (EDT) for the United States are used (EST5EDT is
assumed for TZ).
