ftime(2)ftime(2)NAMEftime - get date and time more precisely
SYNOPSIS
Remarks
This facility is provided for backwards compatibility with Version 7
systems. Either or should be used in new programs.
DESCRIPTION
fills in a structure pointed to by its argument, as defined by
/*
* Structure returned by ftime system call
*/
struct timeb {
time_t time;
unsigned short millitm;
short timezone;
short dstflag;
};
The structure contains the time in seconds since 00:00:00 UTC (Coordi‐
nated Universal Time), January 1, 1970, up to 1000 milliseconds of
more-precise interval, the local timezone (measured in minutes of time
westward from UTC), and a flag that, if nonzero, indicates that Day‐
light Saving time applies locally during the appropriate part of the
year. Consult gettimeofday(2) for more details on the meaning of the
timezone field.
can fail for exactly the same reasons as gettimeofday(2).
WARNINGS
The millisecond value usually has a granularity greater than one due to
the resolution of the system clock. Depending on any granularity (par‐
ticularly a granularity of one) renders code non-portable.
