Don't use it. If the time in seconds +suffices, +.BR time (2) +can be used; +.BR gettimeofday (2) +gives microseconds; +.BR clock_gettime (3) +gives nanoseconds but is not yet widely available. +.LP +Under libc4 and libc5 the \fImillitm\fP field is meaningful. +But early glibc2 is buggy and returns 0 there; +glibc 2.1.1 is correct again. +.SH HISTORY +The +.B ftime() +function appeared in 4.2BSD. +.SH "CONFORMING TO" +BSD 4.2, POSIX 1003.1-2001. +.SH "SEE ALSO" +.BR gettimeofday (2), +.BR time (2) |
