Bug #20797
Updated by nobu (Nobuyoshi Nakada) about 1 month ago
While this raise ArgumentError:
```ruby
Time.new(2024, 12, 25, 0, 0, 0, "+09:99") # ... expected for utc_offset (ArgumentError)
```
This is obviously weird.
```ruby
Time.new(2024, 12, 25, 0, 0, 0, "+09:00:99").strftime("%::z") #=> "+09:01:39"
```
The latter should be an error as well as the former.
