Issue #8941 has been reported by exoth (Yury Trofimenko).

----------------------------------------
Bug #8941: strptime %Y parsing
https://bugs.ruby-lang.org/issues/8941

Author: exoth (Yury Trofimenko)
Status: Open

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.
