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

* Author: Grzegorz Witek
* Status: Open
* Priority: Normal
* Assignee:

----------------------------------------
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"

~~~
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?
