ANSI_SYNOPSIS
9
        #include <time.h>
10
        time_t time(time_t *<[t]>);
11
 
12
TRAD_SYNOPSIS
13
        #include <time.h>
14
        time_t time(<[t]>)
15
        time_t *<[t]>;

DESCRIPTION
18
<<time>> looks up the best available representation of the current
19
time and returns it, encoded as a <<time_t>>.  It stores the same
20
value at <[t]> unless the argument is <<NULL>>.
21
 
22
RETURNS
23
A <<-1>> result means the current time is not available; otherwise the
24
result represents the current time.
25
 
26
PORTABILITY
27
ANSI C requires <<time>>.
28
This function is a wrapper for <<gettimeofday>>; this pollutes the
29
namespace, and should be dealt with in the future.
