Bug #11673: Inconsistent timezone behaviour (Time.parse and DateTime.parse)
https://bugs.ruby-lang.org/issues/11673#change-54813

----------------------------------------
The source of this bug is here: https://github.com/rails/rails/issues/22171#issuecomment-155090007

behaviour between `DateTime.parse` and `Time.parse` is inconsistent when it comes to parsing ISO8601 without letter "Z"

~~~ruby
irb(main):003:0> time = "2015-11-20T03:05:30"
=> "2015-11-20T03:05:30"
irb(main):005:0> Time.parse(time)
=> 2015-11-20 03:05:30 +0800
irb(main):007:0> DateTime.parse(time)
=> #<DateTime: 2015-11-20T03:05:30+00:00 ((2457347j,11130s,0n),+0s,2299161j)>
~~~

Time.parse returns time in local timezone, while `DateTime.parse` returns it in UTC. According to specification, without letter "Z" in the end, the time should be in local timezone (so `Time` class is correct and `DateTime` is wrong)

Is this a bug or for some reason this is intended behaviour?
