NAME

       ftime - get date and time

SYNOPSIS

       #include <sys/timeb.h>

       int ftime(struct timeb *tp);

DESCRIPTION

       The  ftime()  function sets the time and millitm members of the timeb structure pointed to by tp. The structure is defined in <sys/timeb.h>
       and contains the following members:

       time_t		time;
       unsigned short	millitm;
       short		timezone;
       short		dstflag;

       The time and millitm members contain the seconds and milliseconds portions, respectively, of the current time in seconds since 00:00:00 UTC
       (Coordinated Universal Time), January 1, 1970.

       The timezone member contains the local time zone. The dstflag member contains a flag that, if non-zero, indicates that Daylight Saving time
       applies locally during the appropriate part of the year.

       The contents of the timezone and dstflag members of tp after a call to ftime() are unspecified.

RETURN VALUES

       Upon successful completion, the ftime() function returns 0. Otherwise -1 is returned.

ERRORS

       No errors are defined.

USAGE

       For portability to implementations conforming to earlier versions of this document, time(2) is preferred over this function.

       The millisecond value usually has a granularity greater than one due to the resolution of the system clock.  Depending on  any  granularity
       (particularly a granularity of one) renders code non-portable.

NAME

       ftime - get date and time (LEGACY)

SYNOPSIS

       #include <sys/timeb.h>

       int ftime(struct timeb *tp);

DESCRIPTION

       The ftime() function shall set the time and millitm members of the timeb structure pointed to by tp to contain the seconds and milliseconds
       portions, respectively, of the current time in seconds since the Epoch. The contents of the timezone and dstflag members of tp after a call
       to ftime() are unspecified.

       The  system clock need not have millisecond granularity. Depending on any granularity (particularly a granularity of one) renders code non-
       portable.

RETURN VALUE

       Upon successful completion, the ftime() function shall return 0; otherwise, -1 shall be returned.

ERRORS

       No errors are defined.

       The following sections are informative.

EXAMPLES

   Getting the Current Time and Date
       The following example shows how to get the current system time values using the ftime() function. The timeb structure pointed to by  tp	is
       filled with the current system time values for time and millitm.

	      #include <sys/timeb.h>

	      struct timeb tp;
	      int	   status;
	      ...
	      status = ftime(&tp);

APPLICATION USAGE

       For  applications  portability,	the time() function should be used to determine the current time instead of ftime(). Realtime applications
       should use clock_gettime() to determine the current time instead of ftime().

RATIONALE

       None.

FUTURE DIRECTIONS

       This function may be withdrawn in a future version.
