Description:
------------
The 31st of December 2018 is converted to the first week of 2018 instead of the first week of 2019 when using a combination of strototime and date. 

Test script:
---------------
echo date("W-Y", strtotime("2018-12-31T00:00:00Z"))."\n"; //outputs 01-2018 instead of 01-2019
echo date("d-m-Y", strtotime("2018-12-31T00:00:00Z")); // correct calculation

Expected result:
----------------
I expect to see 01-2019 as the output of the first line

using "o" as a parameter in date does the trick and yields expected results
