…me.zone differs from that. The system timezone DST jump hour should not be blacked out by Time.zone.parse if current Time.zone does not do the jump at that time. Fixes rails#5559.

[#5559] Do not black out the system timezone DST jump hour if Time.zone ...

Chrome, Safari and Firefox serialize Date objects to strings such
as 'Mon May 28 2012 00:00:00 GMT-0700 (PDT)'. When these strings
are parsed the zone is interpreted as 'GMT-0700' which doesn't
exist in the TzInfo list of timezones.
By taking advantage of the improved date/time handling in 1.9.3
we can use `Date._parse` and the `:offset` value which is parsed
correctly.
Three tests were amended to make them pass:
1. test_parse_with_old_date
This needed changing to a different value because the original
value was before EST was adopted so was being changed to a
LMT (Local Mean Time) value after the change. It didn't before
because `DateTime` just has offsets from UTC not timezones.
2. test_parse_should_not_black_out_system_timezone_dst_jump
Changed the implementation of this test as the stubs were
dependent on internal implementation details of the test.
Confirmed that the modified test still failed when the
implementation of `parse` was restored to pre-#5571.
3. test_parse_should_black_out_app_timezone_dst_jump
Ditto.
Closes #5770.

...differs from that.
The system timezone DST jump hour should not be blacked out by Time.zone.parse if current Time.zone does not do the jump at that time.
Fixes #5559.
