Chronic 是一个 Ruby 语言用来解析日期数据的开发包。
示例代码：
require 'chronic' Time.now #=> Sun Aug 27 23:18:25 PDT 2006 Chronic.parse('tomorrow') #=> Mon Aug 28 12:00:00 PDT 2006 Chronic.parse('monday', :context => :past) #=> Mon Aug 21 12:00:00 PDT 2006 Chronic.parse('this tuesday 5:00') #=> Tue Aug 29 17:00:00 PDT 2006 Chronic.parse('this tuesday 5:00', :ambiguous_time_range => :none) #=> Tue Aug 29 05:00:00 PDT 2006 Chronic.parse('may 27th', :now => Time.local(2000, 1, 1)) #=> Sat May 27 12:00:00 PDT 2000 Chronic.parse('may 27th', :guess => false) #=> Sun May 27 00:00:00 PDT 2007..Mon May 28 00:00:00 PDT 2007 Chronic.parse('6/4/2012', :endian_precedence => :little) #=> Fri Apr 06 00:00:00 PDT 2012 Chronic.parse('INVALID DATE') #=> nil
