Why doesn't this work?

echo gmdate('Y-m-d H:i:s',strtotime('+7 days','2035-01-01 00:00:00'));

The error I see is:

A non well formed numeric value encountered

The second parameter of strtotime expects a timestamp, not a string. See the manual on strtotime.

You can use strtotime again on your second parameter to get what you want:

echo gmdate('Y-m-d H:i:s',strtotime('+7 days',strtotime('2035-01-01 00:00:00')));
