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.
