Issue #12190 has been updated by Tomoyuki Chikanaga. I wonder if this change could break existing codes. Any thoughts? If there's no real demand, I'll marks this as WONTFIX in 2.3 branch. ---------------------------------------- Bug #12190: DateTime.strptime and Time.strptime does not have compatibility in terms of parsing timezone https://bugs.ruby-lang.org/issues/12190#change-58144 * Author: Naotoshi Seo * Status: Closed * Priority: Normal * Assignee: * ruby -v: ruby 2.3.0p0 (2015-12-25 revision 53290) [x86_64-darwin13] * Backport: 2.1: REQUIRED, 2.2: REQUIRED, 2.3: REQUIRED ---------------------------------------- For CET, only DateTime.strptime successfully parsed timezone ``` irb(main):003:0> DateTime.strptime('2015-11-12 CET', '%Y-%m-%d %Z') => #<DateTime: 2015-11-12T00:00:00+01:00 ((2457338j,82800s,0n),+3600s,2299161j)> irb(main):004:0> Time.strptime('2015-11-12 CET', '%Y-%m-%d %Z') => 2015-11-12 00:00:00 +0900 ``` For JST also, only DateTime worked. ``` irb(main):005:0> ENV['TZ'] = 'UTC' => "UTC" irb(main):006:0> DateTime.strptime('2015-11-12 JST', '%Y-%m-%d %Z') => #<DateTime: 2015-11-12T00:00:00+09:00 ((2457338j,54000s,0n),+32400s,2299161j)> irb(main):007:0> Time.strptime('2015-11-12 JST', '%Y-%m-%d %Z') => 2015-11-12 00:00:00 +0000 ``` For PST, both worked. ``` irb(main):004:0> DateTime.strptime('2015-11-12 PST', '%Y-%m-%d %Z') => #<DateTime: 2015-11-12T00:00:00-08:00 ((2457339j,28800s,0n),-28800s,2299161j)> irb(main):003:0> Time.strptime('2015-11-12 PST', '%Y-%m-%d %Z') => 2015-11-12 00:00:00 -0800 ``` I felt DateTime.strptime and Time.strptime should have compatibility. -- https://bugs.ruby-lang.org/ Unsubscribe: <mailto:ruby-core-request / ruby-lang.org?subject=unsubscribe> <http://lists.ruby-lang.org/cgi-bin/mailman/options/ruby-core>
