Shared information bias is known as the tendency for group members to spend more time and energy discussing information that all members are already familiar with (i.e., shared information), and less time and energy discussing information that only some members are aware of.

FTIME(3)						     Linux Programmer's Manual							  FTIME(3)

NAME
ftime - return date and time SYNOPSIS
#include <sys/timeb.h> int ftime(struct timeb *tp); DESCRIPTION
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 nonzero, 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. RETURN VALUE
This function always returns 0. BUGS
This function is obsolete.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. HISTORY
The ftime() function appeared in 4.2BSD. CONFORMING TO
BSD 4.2, POSIX 1003.1-2001. SEE ALSO
gettimeofday(2), time(2) Linux 2001-12-14 FTIME(3)

NAME
ftime - return date and time SYNOPSIS
#include <sys/timeb.h> int ftime(struct timeb *tp); DESCRIPTION
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 Green- wich). 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.) CONFORMING TO
4.2BSD, POSIX.1-2001. POSIX.1-2008 removes the specification of ftime(). 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(2) gives nanoseconds but is not as widely available. BUGS
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. SEE ALSO
