Do this in your PHP code:

date_default_timezone_set('UTC');

Now PHP operates in UTC. It’s up to you to convert to user local times but you have a common ground.

And in MySQL use UTC_TIMESTAMP() for your DATETIME needs. It uses UTC time regardless of the MySQL settings so you don’t need to worry anymore.
