[ruby-core:74897] [Ruby trunk Bug#12273] Time.parse incorrectly parses Russian months

Issue #12273 has been updated by Victor Shepelev.


> Thanks. So what should I use to parse dates in Russian?

There's no easy way, unfortunately. For simple formats you can try to just `gsub` Russian monthnames into English and then use normal `Time.parse`.

Not a Ruby bug, definitely :)

----------------------------------------
When parsing dates in Russian where day number is 31, `Time.parse` returns `2016-05-01`. No matter what month or year is provided.
31 march 2016:

```
irb(main):003:0> require "time"
=> true
irb(main):004:0> Time.parse "31 марта 2016"
=> 2016-05-01 00:00:00 +0300
irb(main):005:0> Time.parse "31 march 2016"
=> 2016-03-31 00:00:00 +0300
irb(main):006:0> Time.parse "31 mars 2016"
=> 2016-03-31 00:00:00 +0300
```

31 december 2013:

```
irb(main):013:0> Time.parse "31 декабря 2013"
=> 2016-05-01 00:00:00 +0300
irb(main):014:0> Time.parse "31 december 2013"
=> 2013-12-31 00:00:00 +0400
```
