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.
