Subject: [ruby-dev:51192] [Ruby master Bug#18946] Time#to_date returns incorrect date

Issue #18946 has been updated by matz (Yukihiro Matsumoto).


I checked commit history and found out that to_date has been use GREGORIAN calendar since 2011-05-31 and to_datetime preserved the old DEFAULT_SG (ITALY). I assume this is a mistake and both should use GREGORIAN (ext/date/date_core.c:8647).
