/**
* Test some critical TZ/DST.
*
* This method tests some special TZ/DST combinations that were fixed
* by MDL-38999. The tests are done by comparing the results of the
* output using Moodle TZ/DST support and PHP native one.
*
* Note: If you don't trust PHP TZ/DST support, can verify the
* harcoded expectations below with:
* http://www.tools4noobs.com/online_tools/unix_timestamp_to_datetime/
