    initial v1  
    33The original phpdoc for the function hints at the bug: "Simply adds the value of gmt_offset." This is not sufficient to be DST aware. The point of DST is that gmt_offset changes throughout the year, so simply adding the offset to any date will be incorrect for ~50% of dates.

    5 Note that the dual function `get_gmt_from_date` uses the `timezone_string` option and the `DateTime` class to properly respect the timezone, as alluded to in #20398. This is why the second test `test_dst_respected_getting_gmt_date` passes.

    77The patch to `get_date_from_gmt` adds the same functionality, so that the `timezone_string` is used to convert the GMT date into a date local to that timezone, which respects DST where relevant. The patch only alters `get_gmt_from_date` to unify the logic between both functions and use `DateTime` properly.
