The latest version of this topic can be found at _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   


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.

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.)

Fraction of a second in milliseconds.

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

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 23:59:59 January 18, 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.
