Category set to lib Status changed from Open to Assigned Assignee set to tadf (tadayoshi funaba) ---------------------------------------- Bug #8941: strptime %Y parsing https://bugs.ruby-lang.org/issues/8941#change-41939 Author: exoth (Yury Trofimenko) Status: Assigned Priority: Normal Assignee: tadf (tadayoshi funaba) Category: lib Target version: ruby -v: ruby 2.0.0p247 (2013-06-27 revision 41674) [x86_64-linux] Backport: 1.9.3: UNKNOWN, 2.0.0: UNKNOWN Time.strptime("1", "%Y") => 0001-01-01 00:00:00 +0642 Is it expected behavior? strftime docs say this: # %Y - Year with century (can be negative, 4 digits at least) # -0001, 0000, 1995, 2009, 14292, etc. So I would expect it to parse only 4 digits as well, as when some parsed data changes format from 2013 to 13 I would better get an error, but I just get 0013 year. By the way, Python's strptime seems to accept only 4 digit years. -- http://bugs.ruby-lang.org/
