This +value is not the same as the actual number of seconds between the time +and the Epoch, because of leap seconds and because clocks are not +required to be synchronised to a standard reference. The intention is +that the interpretation of seconds since the Epoch values be +consistent; see POSIX.1 Annex B 2.2.2 for further rationale. +.SH "CONFORMING TO" +SVr4, SVID, POSIX, X/OPEN, BSD 4.3 +.br +Under BSD 4.3, this call is obsoleted by +.BR gettimeofday (2). +POSIX does not specify any error conditions. +.SH "SEE ALSO" +.BR date (1), +.BR gettimeofday (2), +.BR ctime (3), +.BR ftime (3) |
