Subject: [ruby-dev:51192] [Ruby master Bug#18946] Time#to_date returns incorrect date
Date: Mon, 08 Aug 2022 03:02:37 +0000 (UTC) [thread overview]
Message-ID: <redmine.journal-98596.20220808030237.52442@ruby-lang.org> (raw)
In-Reply-To: <redmine.issue-18946.20220729062905.52442@ruby-lang.org>
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).
Matz.
