如何在Ruby中執行timedelta和日期比較？

Question

在Python，如果我想檢查+ 24小時過後的具體日期，我會寫：

from datetime import datetime, timedelta 

some_date = datetime(2013, 1, 10, 11, 0) 
day = timedelta(1) 

# Checks if some_date + 1 day is before today's date 
print some_date + day < datetime.now() 

我怎麼能當一個特定的日期+1天建設1天，檢查的時間差在Ruby今天的日期之前？

Answer 1

require 'time' 

xmas = DateTime.new(2013, 12, 25) 
puts x = xmas + 1 # 2013-12-26T00:00:00+00:00 
d = DateTime.now 
puts x > d  # true 
puts x - d  # 30167183979194791/86400000000000 (a Rational) 
puts d >> 12  # 2014-01-10T21:15:20+01:00
