+FUNCTION
+<<time>>---get current calendar time (as single number)
+
+INDEX
+	time
+
+ANSI_SYNOPSIS
+	#include <time.h>
+	time_t time(time_t *<[t]>);
+
+TRAD_SYNOPSIS
+	#include <time.h>
+	time_t time(<[t]>)
+	time_t *<[t]>;
+
+DESCRIPTION
+<<time>> looks up the best available representation of the current
+time and returns it, encoded as a <<time_t>>.  It stores the same
+value at <[t]> unless the argument is <<NULL>>.
+
+RETURNS
+A <<-1>> result means the current time is not available; otherwise the
+result represents the current time.
+
+PORTABILITY
+ANSI C requires <<time>>.
+
+Supporting OS subroutine required: Some implementations require
+<<gettimeofday>>.
