NAME

ftime - get date and time

SYNOPSIS

#include <sys/timeb.h>
int ftime(struct timeb *tp);

DESCRIPTION

The ftime() function sets the time and millitm members of the timeb structure pointed to by tp. The structure is defined in <sys/timeb.h> and contains the following members:

time_t           time;
unsigned short   millitm;
short            timezone;
short            dstflag;

The time and millitm members contain the seconds and milliseconds portions, respectively, of the current time in seconds since 00:00:00 UTC (Coordinated Universal Time), January 1, 1970.

The timezone member contains the local time zone. The dstflag member contains a flag that, if non-zero, indicates that Daylight Saving time applies locally during the appropriate part of the year.

The contents of the timezone and dstflag members of tp after a call to ftime() are unspecified.

RETURN VALUES

Upon successful completion, the ftime() function returns 0. Otherwise −1 is returned.

ERRORS

No errors are defined.

USAGE

For portability to implementations conforming to earlier versions of this document, time(2) is preferred over this function.

The millisecond value usually has a granularity greater than one due to the resolution of the system clock. Depending on any granularity (particularly a granularity of one) renders code non-portable.
