Python基礎教程：datetime模塊

import datetime 
now = datetime.datetime.now() 
print now 
#往後3小時，2天，3分鐘，3秒鐘 
print datetime.datetime.now() + datetime.timedelta(hours=3) 
print datetime.datetime.now() + datetime.timedelta(days=3) 
print datetime.datetime.now() + datetime.timedelta(minutes=3) 
print datetime.datetime.now() + datetime.timedelta(seconds=3)
