From manual page: https://php.net/function.date

The manual page says that the format character O (capital letter o) represents "difference to Greenwich time (GMT) in hours", but the example says +0200, which I would describe as is 100 times greater than the time difference (and what it, after some testing, seems to actually do). It could also be interpreted as GMT offset by 200 hours (little over a week).

The bigger mystery is what the two trailing zeros do. I asumed they represent centiminutes (going from 00-99) since the documentation doesn't say anything about minutes. By running the following script, they turned out to be minutes (00-59).


Test script:
---------------
<?php
// Set timezone to UTC-03:30
date_default_timezone_set("America/St_Johns");
echo date("O");
?>


Expected result:
----------------
-0350

Actual result:
--------------
-0330
