how to generate random time, pls?

say i need random time between 01-01-1970 to 12-31-2012,
how to do, pls?

 

how about this?
echo date("Y/m/d",mt_rand(0,time()));

 

sorry the above us random to current days date, to end 2012it would be
echo date("Y/m/d",mt_rand(0,13569048001));

 

how about random time from 01-01-1970 to current?
how do you get 13569048001?

 

$timestamp1 = strtotime('01-01-1970');
$timestamp2 = strtotime('31-12-2012');
echo "timestamp 1 (01-01-1970) : ".$timestamp1."<br />timestamp 2 (31-12-2012) : ".$timestamp2;
 
$rand_timestamp = rand(-3600, 1356908400);
$rand_date = date('d-m-Y', $rand_timestamp);
echo "<br />random date between 01-01-1970 and 31-12-2012 : ".$rand_date;
 
$now_timestamp = time();
$rand_timestamp_till_now = rand(-3600, $now_timestamp);
$rand_date_till_now = date('d-m-Y', $rand_timestamp_till_now);
echo "<br />random date between 01-01-1970 and NOW : ".$rand_date_till_now;

PHP:

 

simpler example:

<?php
 
$timestamp = strtotime('2012-12-31');
 
// unix timestamp for 1970-01-01 is => 0
 
$result = rand(0, $timestamp);
 
print date('Y/m/d h:i:s', $result);
 
?>
