_ftime, _ftime32, _ftime64

Get the current time. More secure versions of these functions are available; see _ftime_s, _ftime32_s, _ftime64_s.

void _ftime( 
   struct _timeb *timeptr 
void _ftime32( 
   struct __timeb32 *timeptr 
void _ftime64( 
   struct __timeb64 *timeptr 


  • timeptr
    Pointer to a _timeb,__timeb32 or __timeb64 structure.


The _ftime function gets the current local time and stores it in the structure pointed to by timeptr*.* The _timeb, __timeb32,and__timeb64 structures are defined in SYS\Timeb.h. They contain four fields, which are listed in the following table.

  • dstflag
    Nonzero if daylight savings time is currently in effect for the local time zone. (See _tzset for an explanation of how daylight savings time is determined.)

  • millitm
    Fraction of a second in milliseconds.

  • time
    Time in seconds since midnight (00:00:00), January 1, 1970, coordinated universal time (UTC).

  • timezone
    Difference in minutes, moving westward, between UTC and local time. The value of timezone is set from the value of the global variable _timezone (see _tzset).

_ftime64, which uses the __timeb64 structure, allows file-creation dates to be expressed up through 23:59:59, December 31, 3000, UTC; whereas _ftime32 only represents dates through 03:14:07 January 19, 2038, UTC. Midnight, January 1, 1970, is the lower bound of the date range for all these functions.

_ftime is equivalent to _ftime64 and _timeb contains a 64-bit time. This is true unless _USE_32BIT_TIME_T is defined, in which case the old behavior is in effect; _ftime uses a 32-bit time and _timeb contains a 32-bit time.

_ftime validates its parameters. If passed a null pointer as timeptr, the function invokes the invalid parameter handler, as described in Parameter Validation. If execution is allowed to continue, the function sets errno to EINVAL.
