If I try to parse a string generated by javascript's new Date() (seems like RFC 2822 with timezone name specified) in a browser located in Asia/Novosibirsk timezone I will get 1st of November quite frequently.

require 'time'
Time.parse('Mon May 18 2015 22:16:38 GMT+0600 (NOVT)')
# => 2015-11-01 22:16:38 +0600

It seems that Date._parse recognizes NOV as November.

% ruby -rdate -e 'p Date._parse("Mon May 18 2015 22:16:38 GMT+0600 (NOVT)")[:mon]'
11
% ruby -rdate -e 'p Date._parse("Mon May 18 2015 22:16:38 GMT+0600")[:mon]'       
5
% ruby -v
