Subject: [ruby-dev:51194] [Ruby master Bug#18946] Time#to_date returns incorrect date

Issue #18946 has been updated by nobu (Nobuyoshi Nakada).


Fixed this issue itself, but turned out Psych had a related issue.
The YAML spec doesn’t considered the calendar systems.
Although I [reported], as it hasn’t been concluded yet, the failing test is excluded now at commit:git|79fdf9712dea4943a15c4ef34348b1a159b62f4a.
