ftime - return date and time
Návod, kniha: Linux Programmer's Manual
#include <sys/timeb.h>
int ftime(struct timeb *tp);
Return current date and time in
tp, which is declared as follows:
struct timeb {
time_t time;
unsigned short millitm;
short timezone;
short dstflag;
};
Here
time is the number of seconds since the epoch,
millitm is the
number of milliseconds since
time seconds since the epoch,
timezone is the local time zone measured in minutes of time west of
Greenwich, and
dstflag is a flag that, if nonzero, indicates that
Daylight Saving time applies locally during the appropriate part of the year.
These days the contents of the
timezone and
dstflag fields are
undefined.
This function always returns 0.
This function is obsolete. Don't use it. If the time in seconds suffices,
time(2) can be used;
gettimeofday(2) gives microseconds;
clock_gettime(3) gives nanoseconds but is not yet widely available.
Under libc4 and libc5 the
millitm field is meaningful. But early glibc2
is buggy and returns 0 there; glibc 2.1.1 is correct again.
The
ftime() function appeared in 4.2BSD.
BSD 4.2, POSIX 1003.1-2001.
gettimeofday(2),
time(2)
