This PHP statement date('Y-m-d',1281394800) returns different values in different servers. One gives me 2010-08-09 and the other 2010-08-10. Could someone please help explain?
Try this and see if you still get different results:
date_default_timezone_set('UTC');
echo date('Y-m-d',1281394800);
If you get exactly the same results across servers, you can set the timezone to the one you want. For more information:
Are the servers in (or configured with) different timezones?
date()'s output is timezone-dependent.
Set the time zone:
date_default_timezone_set('UTC');
echo date('Y-m-d',1281394800);
date_default_timezone_set — Sets the default timezone used by all date/time functions in a script
