ftime — return date and time
#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 non-zero, 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This function is obsolete.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.
