# pcj
import time
# print(time.localtime())
# print(time.time())
# #print(help(time))   #获取time的帮助
# #time.sleep(1)   #睡几秒
# print(time.gmtime(10000000000))   # convert seconds since Epoch to UTC tuple  标准时间  utc时区
# print(time.localtime()) #convert seconds since Epoch to local time tuple   本地时间  ，里面可以传值 utc+8
x=time.localtime()
# print(x.tm_year)   #取出当时的年
# print(time.localtime().tm_year)#取出当时的年
# print(x.tm_mon)  #取出月
# print(x.tm_mday)   #取时日期
# print(time.mktime(x))  #把一个元组时间，转换为时间戳
# print(time.strftime("%Y-%m-%d %H:%M:%S",x))  #格式化时间
# print(time.strftime("%m"))
print(time.strptime("2019-06-16 11:41:53","%Y-%m-%d %H:%M:%S")) #把格式化的时间转换为元组
print(x.tm_hour,‘:‘,x.tm_min)
print(time.asctime())  # Convert a time tuple to a string, e.g. ‘Sat Jun 06 16:26:11 1998‘.
                         #When the time tuple is not present, current time as returned by localtime()
                       #is used.

print(time.ctime())    #Convert a time in seconds since the Epoch to a string in local time.
                        # This is equivalent to asctime(localtime(seconds)). When the time tuple is
                        #  not present, current time as returned by localtime() is used.


datetime模块

import datetime
print(datetime.datetime.now())   #打印当前时间now()表示当前
print(datetime.datetime.now()+datetime.timedelta(3))   #当音时间三天前
print(datetime.datetime.now()+datetime.timedelta(-3))  #当音时间三天后
print(datetime.datetime.now()+datetime.timedelta(hours=2))  #当音时间2小时后
print(datetime.datetime.now()+datetime.timedelta(minutes=10))  #当音时间10分钟后
