time与datetime模块

import time
print(time.time()) # 当前时间戳
print(time.altzone) # 与格林威治相差的时间
print(time.asctime()) # Sat Feb 18 15:12:23 2017
print(time.localtime(time.time()-(60*60*24))) # 时间对象，time.localtime().tm_year 返回2017
print(time.gmtime(time.time()+(60*60*24))) # 格林威治utc时间对象
print(time.ctime()) #Sat Feb 18 15:23:02 2017
# print(time.strftime('%Y-%m-%d %H:%M:%S',时间对象如localtime)) # 定义时间格式
# 时间转成时间戳
stuct_time = time.strptime('2017-02-17','%Y-%m-%d') # 时间对象
print(time.mktime(stuct_time))

# 时间戳转成时间
