I have a timestamp value from PHP: 1188604800000
1188604800000
When I format the time to human readable like this:
date(\"m/d/Y\", 1188604800000)
PHP uses seconds-based timestamps, so divide 1188604800 by 1000 and you are good.
1188604800
1000
php> echo date('Y-m-d', 1188604800000/1000); 2007-09-01
