Python Module-time module

Time.time (): Returns the timestamp of the current time

>>> time.time () 1518789643.737527

Time.localtime ([secs]): Converts a timestamp to the struct_time of the current time zone. secs parameter if not provided, whichever is the current time

>>> time.time () 1518790500.354652>>> time.localtime () time.struct_time (tm_year=2018, tm_mon=2, tm_ Mday=16, tm_hour=22, tm_min=15, tm_sec=3, tm_wday=4, tm_yday=47, tm_isdst=0) >>> Time.localtime ( 1518790500.354652) Time.struct_time (tm_year=2018, tm_mon=2, tm_mday=16, tm_hour=22, tm_min=15, tm_sec=0, Tm_wday=4, TM _yday=47, tm_isdst=0)

Time.gmtime ([secs]): Similar to the LocalTime () method, the Gmtime () method is to convert a timestamp to a struct_time of UTC time Zone (0 o'clock Zone), eight hours later than China

>>> Time.gmtime (Time.struct_time) (tm_year=2018, tm_mon=2, tm_mday=16, tm_hour=14, tm_min=16, tm_sec=49, tm_ Wday=4, tm_yday=47, tm_isdst=0) >>> time.gmtime (1518790500.354652) time.struct_time (tm_year=2018, tm_mon=2, Tm_mday=16, tm_hour=14, tm_min=15, tm_sec=0, tm_wday=4, tm_yday=47, tm_isdst=0)

Time.mktime (t): Converts a struct_time to a timestamp

>>> Time.mktime (Time.localtime ()) 1518790773.0>>> Time.mktime (Time.localtime ()) 1518790779.0

Time.sleep (secs): Thread delays a specified time to run, that is, sleep, in seconds

>>> Time.sleep (3)  #睡眠3秒

Time.asctime ([t]): A tuple or struct_time representing time is represented in this form: Fri Feb 16 22:54:04 2018. If there are no parameters, the Time.localtime () will be passed in as a parameter

>>> time.asctime () ' Fri Feb 16 22:56:13 2018 '

Time.ctime ([secs]): Converts a timestamp (floating point number in seconds) to the form of Time.asctime (). If the parameter is not given or is none, the default Time.time () is the parameter. Its role is equivalent to Time.asctime (time.localtime (secs))

>>> time.time () 1518793099.0701997>>> time.ctime () ' Fri Feb 22:58:33 2018 ' >>> time.ctime ( 1518793099.0701997) ' Fri Feb 16 22:58:19 2018 '

Time.strftime (format[, T]): Converts a tuple or struct_time representing time into a formatted time string. If T is not specified, the Time.localtime () is passed in

>>> time.strftime ('%y-%m-%d%h:%m:%s ') ' 2018-02-16 23:26:38 ' >>> time.strftime ('%y-%m-%d%h:%m:%s ', Time.localtime ()) ' 2018-02-16 23:26:52 ' >>> time.strftime ('%y-%m-%d%h:%m:%s ', Time.localtime ( 1518793099.0701997)) ' 2018-02-16 22:58:19 '

Time.strptime (string[, format]): Converts a formatted time string to Struct_time, and strftime () is an inverse operation

>>> time.strptime (' 2018-2-16 23:28:43 ', "%y-%m-%d%h:%m:%s") time.struct_time (tm_year=2018, tm_mon=2, tm_ Mday=16, tm_hour=23, tm_min=28, tm_sec=43, tm_wday=4, tm_yday=47, Tm_isdst=-1)
