 NAME

   utc_anyzone - Gets the time zone label and offset from GMT

 SYNOPSIS

   #include <dce/utc.h>

   int utc_anyzone( char *tzname,
                    size_t tzlen,
                    long *tdf,
                    int *isdst,
                    const utc_t *utc );

 PARAMETERS

   Input

   tzlen
       Length of the tzname buffer.

   utc
       Binary timestamp. Use NULL if you want this routine to use the
       current time for this parameter.

   Output

   tzname
       Character string that is long enough to hold the time zone label.

   tdf
       Longword with differential in seconds east of GMT.

   isdst
       Integer with a value of -1, indicating that no information is
       supplied as to whether it is standard time or daylight saving
       time. A value of -1 is always returned.

 DESCRIPTION

   The utc_anyzone() routine gets the time zone label and offset from
   GMT by using the TDF contained in the utc input parameter. The label
   returned is always of the form GMT+n or GMT-n where n is the tdf
   expressed in hours:minutes. (The label associated with an arbitrary
   time zone is not known; only the offset is known.)

 NOTES

   All of the output parameters are optional.  No value is returned and
   no error occurs if the pointer is NULL.

 RETURN VALUES

    0    Indicates that the routine executed successfully.

   -1    Indicates an invalid time argument or an insufficient buffer.

 EXAMPLES

   See the sample program in the utc_anytime reference page.
