Comment (by Rarst):

 > The bug has changed from the DateTime component to the logic structured
 in options-general.php.
 the syntax UTC, Etc/GMT or any other synonym that has an offset 0 is
 considered a manual offset and in this case a manual offset regardless of
 its value does not have a Daylight saving time

 I don't follow what do you consider a bug at this point. Please talk in
 specific examples of settings state, actual output, and output you think
 should be correct instead.

 Etc/GMT (and other deprecated zones) are not supported by core and cannot
 be selected in settings.

 Adding things to Unix timestamps - no, we are done doing that and
 `wp_date()` is written to work with real timestamps as is. I don't follow
 what output are you trying to achieve there.

 Memory thing doesn't seem relevant, this is one-off page execution and it
 hardly matters if we try to release small amount of memory early.
