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>>.
This function is a wrapper for <<gettimeofday>>; this pollutes the
namespace, and should be dealt with in the future.
