 get_gmt_from_date uses `DateTime` class (albeit in a rather horrible way)
 to respect DST differences. The dual function get_date_from_gmt does not
 do the reverse. Hence:

 {{{
 var_dump(get_date_from_gmt('2012-02-01 12:00:00'));
 }}}

 Will return `'2012-02-01 12:00:00'` if in `Europe/London` outside DST, but
 `'2012-02-01 13:00:00'` inside DST.

 Bug was noticed with RSS importer plugin which uses this function. If the
 core behaviour is by design (i.e. no intention for DST support on this
 function) then I will open another bug there.
