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This function is obsolete.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.
