.SH DESCRIPTION
.BR time ()
returns the time as the number of seconds since the
Epoch, 1970-01-01 00:00:00 +0000 (UTC).
-.PP
+.P
If
.I tloc
is non-NULL,
required to be synchronized to a standard reference.
The intention is that the interpretation of seconds since the Epoch values be
consistent; see POSIX.1-2008 Rationale A.4.15 for further rationale.
-.PP
+.P
On Linux, a call to
.BR time ()
with
the Epoch, so the C library wrapper function never sets
.I errno
as a result of this call.
-.PP
+.P
The
.I tloc
argument is obsolescent and should always be NULL in new code.
