Issue #9794 has been updated by tadayoshi funaba. ずっと俺には何の決定権もないって言われ続けているような気がしたけど 今日は本当にそれを実感した。 ---------------------------------------- Bug #9794: DateTime.strptime() doesn't work correctly for '%s %z' https://bugs.ruby-lang.org/issues/9794#change-46509 * Author: Felipe Contreras * Status: Rejected * Priority: Low * Assignee: tadayoshi funaba * Category: ext * Target version: * ruby -v: 2.1.1p76 * Backport: 2.0.0: UNKNOWN, 2.1: UNKNOWN ---------------------------------------- Time.strptime() works correctly: Time.strptime('0 +0100', '%s %z').strftime('%s %z') => "0 +0100" But DateTime.strptime() doesn't: DateTime.strptime('0 +0100', '%s %z').strftime('%s %z') => "0 +0000" In Rubinious it does work correctly: DateTime.strptime('0 +0100', '%s %z').strftime('%s %z') => "0 +0100" This make the RubySL date space fail: DateTime#strptime parses seconds and timezone correctly FAILED Expected "1970-01-01T00:00:00+00:00" to equal "1970-01-01T01:00:00+01:00" In addition, both C and perl preserver the offset correctly when doing '%s %z'. So it's very clear DateTime.strptime() has to be fixed. Patch attached. ---Files-------------------------------- 0001-datetime-fix-strptime-s-z.patch (1.94 KB) -- https://bugs.ruby-lang.org/
