 5 print(datetime.datetime.now() + datetime.timedelta(weeks=3)) # 三周后
 6 print(datetime.datetime.now() + datetime.timedelta(weeks=-3)) # 三周前
 7 print(datetime.datetime.now() + datetime.timedelta(days=-3)) # 三天前
 8 print(datetime.datetime.now() + datetime.timedelta(days=3)) # 三天后

10 print(datetime.datetime.now() + datetime.timedelta(hours=-5)) # 5小时前
11 print(datetime.datetime.now() + datetime.timedelta(minutes=-15)) # 15分钟前
12 print(datetime.datetime.now() + datetime.timedelta(minutes=15)) # 15分钟后
13 print(datetime.datetime.now() + datetime.timedelta(seconds=-70)) # 70秒前

16 current_time = datetime.datetime.now()
17 # 可直接调整到指定的 年 月 日 时 分 秒 等

19 print(current_time.replace(year=1977))  # 直接调整到1977年
20 print(current_time.replace(month=1))  # 直接调整到1月份
21 print(current_time.replace(year=1989,month=4,day=25))  # 1989-04-25 18:49:05.898601
