Time.localtime (p_tuple) #将struct格式的时间转换成时间戳

Print (Time.mktime (Time.localtime ())) 1465611464.0# parameter: Time in p_tuple:struct format

Time.strftime (format,p_tuple) #将struct格式的时间用format给定的格式打印

Print (Time.strftime ("%y-%m-%d%h:%m:%s", Time.localtime ())) 2016-06-11 10:21:20# parameter 1 format  : Formatting for the given time # parameter 2  p_ Time in tuple:struct format

Print (Time.strptime (' 2016-06-05 ', '%y-%m-%d '))  time.struct_time (tm_year=2016, tm_mon=6, tm_mday=5, tm_hour=0, Tm_min=0, Tm_sec=0, tm_wday=6, tm_yday=157, tm_isdst=-1) #参数1  string: The given date # parameter 2  format: Formatting of the given date

2. DateTime module

Datetime.date.today () #返回当前日期, format 2016-06-05

Print (Datetime.date.today ()) 2016-06-11

Datetime.date.fromtimestamp (cls,timestamp) #将时间戳转换成 xx-xx-xx format and returns

Print (Datetime.date.fromtimestamp (Time.time ())) 2016-06-11# parameter  timestamp: timestamp

Datetime.datetime.now () #返回当前时间2016-06-05 18:23:30.819466, time plus minus

Print (Datetime.datetime.now ())     2016-06-11 10:57:57.825386new_date = Datetime.datetime.now () + Datetime.timedelta (days=10)     #比现在加10天new_date = Datetime.datetime.now () + Datetime.timedelta (days=-10)    # Minus 10 days than now new_date = Datetime.datetime.now () + Datetime.timedelta (hours=-10)   #比现在减10小时new_date = Datetime.datetime.now () + Datetime.timedelta (seconds=120) #比现在 +120s

Time comparison: True if a match is returned

Current_time= Datetime.datetime.now () time_obj = Current_time.replace (2014,9,12) print (current_time>time_obj)                                #date时间可以相互比较print (str (current_time) > ' 2014-09-12 18:37:26.879790 ')     #可以比较
