ftime3
Return date and time
Usage
#include <sys/timeb.h>
[[deprecated]] int ftime(struct timeb *tp);
Library
Standard C library (libc, -lc)
Overview
NOTE: This function is no longer provided by the GNU C library. Use clock_gettime(2) instead.
This function returns the current time as seconds and milliseconds since the Epoch, 1970-01-01 00:00:00 +0000 (UTC). The time is returned 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, and millitm is the number of milliseconds since time seconds since the Epoch. The timezone field is the local timezone measured in minutes of time west of Greenwich (with a negative value indicating minutes east of Greenwich). The dstflag field is a flag that, if nonzero, indicates that Daylight Saving time applies locally during the appropriate part of the year.
POSIX.1-2001 says that the contents of the timezone and dstflag fields are unspecified; avoid relying on them.
Return value
This function always returns 0. (POSIX.1-2001 specifies, and some systems document, a -1 error return.)
