Style/DateTime wrongly triggered on classes ...::DateTime

[doits]

I've a file with the following line:

Icalendar::Values::DateTime.new(start_at)

It gives me the following error:

Style/DateTime: Prefer Date or Time over DateTime.

In this case it is wrong, because Icalendar::Values::Time is totally different from Icalendar::Values::DateTime (first does not include the date at all).

I think the linter should only be triggered on /\b(::)?DateTime\b/ and ignore other things. Or am I missing something?

---

Expected behavior

Icalendar::Values::DateTime.new(start_at) should not trigger Style/DateTime

Actual behavior

It trigger Style/DateTime

Steps to reproduce the problem

Lint a file with Icalendar::Values::DateTime.new(start_at).

RuboCop version

Include the output of rubocop -V. Here's an example:

$ rubocop -V
0.51.0 (using Parser 2.4.0.0, running on ruby 2.4.2 x86_64-darwin17)

Yep. There's no reason we should register an offense on a qualified DateTime in another namespace. 🙂
