Create and consume millisecond timestamps in PHP and Groovy

timestamp.groovy

// Consume timestamp in Java/Groovy
def timestamp = ...
def date = new Date(timestamp)
println new java.text.SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(date)

// Generate milliseconds in Groovy for current date
def timestamp = new Date().getTime()

timestamp.php

<?php

// Generate milliseconds in PHP for current date
$timestamp = floor(microtime(true) * 1000);

// Consume the timestamp in PHP
// NOTE: date needs the resolution of the timestamp to be seconds not milliseconds
$timestamp = ...
echo date('Y-m-d H:i:s', floor($timestamp / 1000));
