PHP
===

php > $status_id = '184846323277770752';
php > $timestamp = ($status_id >> 22);
php > echo $timestamp;
511
php > $timestamp = ($status_id >> 22) + '1288834974657';
php > echo $timestamp;
1288834975168

The integer value of var on success, or 0 on failure. Empty arrays return 0, non-empty arrays return 1.

The maximum value depends on the system. 32 bit systems have a maximum signed integer range of -2147483648 to 2147483647. So for example on such a system, intval('1000000000000') will return 2147483647. The maximum signed integer value for 64 bit systems is 9223372036854775807.

Strings will most likely return 0 although this depends on the leftmost characters of the string. The common rules of integer casting apply. 

Ah, en 64 bits hasta el bitwise anda. Todavia no resolví la parte de la conversión de tiempos. Supongo que date() alcanza, indeed:

php > $timestamp = 1332905772405/1000;
php > echo date('Y-m-d', $timestamp);
2012-03-28

El quid es obtener un $timestamp valido, con un INT valido.

php > print PHP_INT_MAX;
2147483647
