+.Sh SYNOPSIS
+.In time.h
+.Ft time_t
+.Fn time "time_t *tloc"
+.Sh DESCRIPTION
+The
+.Fn time
+function
+returns the value of time in seconds since 0 hours, 0 minutes,
+0 seconds, January 1, 1970, Coordinated Universal Time.
+If an error occurs,
+.Fn time
+returns the value
+.Po Vt time_t Pc Ns \-1 .
+.Pp
+The return value is also stored in
+.No \&* Ns Va tloc ,
+provided that
+.Va tloc
+is non-null.
+.Sh ERRORS
+The
+.Fn time
+function may fail for any of the reasons described in
+.Xr gettimeofday 2 .
+.Sh SEE ALSO
+.Xr gettimeofday 2 ,
+.Xr ctime 3
+.Sh STANDARDS
+The
+.Nm
+function conforms to
+.St -p1003.1-2001 .
+.Sh HISTORY
+A
+.Fn time
+function appeared in
+.At v6 .
+.Sh BUGS
+Neither
+.St -isoC-99
+nor
+.St -p1003.1-2001
+requires
+.Fn time
+to set
+.Va errno
+on failure; thus, it is impossible for an application to distinguish
+the valid time value \-1 (representing the last UTC second of 1969)
+from the error return value.
+.Pp
+Systems conforming to earlier versions of the C and
+.Tn POSIX
+standards (including older versions of
+.Fx )
+did not set
+.No \&* Ns Va tloc
+in the error case.
