FTIME(P)						     POSIX Programmer's Manual							  FTIME(P)

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       This function may be withdrawn in a future version.

PROLOG

       This  manual page is part of the POSIX Programmer's Manual.  The Linux implementation of this interface may differ (consult the correspond-
       ing Linux manual page for details of Linux behavior), or the interface may not be implemented on Linux.

NAME

       gettimeofday - get the date and time

SYNOPSIS

       #include <sys/time.h>

       int gettimeofday(struct timeval *restrict tp, void *restrict tzp);

DESCRIPTION

       The gettimeofday() function shall obtain the current time, expressed as seconds and microseconds since the  Epoch,  and	store  it  in  the
       timeval structure pointed to by tp. The resolution of the system clock is unspecified.

       If tzp is not a null pointer, the behavior is unspecified.

RETURN VALUE

       The gettimeofday() function shall return 0 and no value shall be reserved to indicate an error.

ERRORS

       No errors are defined.

       The following sections are informative.

EXAMPLES

       None.

APPLICATION USAGE

       None.

RATIONALE

       None.

FUTURE DIRECTIONS

       None.
