Misc #19096: [Question] Time with `-00:00` offset is in UTC

It's a bit unexpected but

```ruby
Time.new(2022, 1, 1, 0, 0, 0, "-00:00").utc?
# => true
```

But time with `+00:00` or `0` offset is treated as not UTC time:

```ruby
Time.new(2022, 1, 1, 0, 0, 0, "+00:00").utc? # => false
Time.new(2022, 1, 1, 0, 0, 0, 0).utc? # => false
```

Is it an intentional behaviour? In this case could you please clarify the reason why it works this way?
