Python Time and Datatime modules

Time and Datatime modules

Time-related operations, time is represented in three ways:

• Timestamp after January 1, 1970 seconds, i.e.: Time.time ()
• Formatted string 2014-11-11 11:11, i.e.: Time.strftime ('%y-%m-%d ')
• Structured time tuples include: year, day, week, etc. time.struct_time is: time.localtime ()

Import time# return processor Time, 3.3 is obsolete, changed to Time.process_time () measurement processor time, not including sleep time, unstable, Mac on the test print (Time.clock ()) Print ( Time.process_time ()) input result: 1.520822339055174e-060.09360059999999999

Import time# Returns the time difference from UTC, in seconds, for print (time.altzone) input results: 32400

Import time# return time format "Thu Oct 17:26:06" Print (Time.asctime ()) input result: Thu 30 16:53:21 2017

Import time# Returns the struct time object format for local times print (Time.localtime ()) input result: Time.struct_time (tm_year=2017, tm_mon=11, tm_mday=30 , Tm_hour=16, tm_min=53, tm_sec=21, tm_wday=3, tm_yday=334, tm_isdst=0)

Import time# return time format "Fri 11:14:16" Print (Time.asctime (Time.localtime ())) # Return time format "Fri-11:14:16" Print (Time.ctime ()) input result: Thu 16:53:21 2017Thu 30 16:53:21 2017

Import time# Returns the Struc Time Object format for UTC time Print (Time.gmtime (Time.time ()-800000)) input result: Time.struct_time (tm_year=2017, tm_mon= One, tm_mday=21, tm_hour=2, tm_min=40, Tm_sec=1, Tm_wday=1, tm_yday=325, tm_isdst=0)

Import time# # Date string to timestamp  # # Convert date string to struct time object Format string_2_struct = Time.strptime ("2016/06/22", "%y/%m/%d") print (s tring_2_struct) string_2_struct = Time.strptime ("2016.06.22", "%y.%m.%d") print (string_2_struct) input result: time.struct_ Time (tm_year=2016, tm_mon=6, tm_mday=22, tm_hour=0, tm_min=0, tm_sec=0, tm_wday=2, tm_yday=174, Tm_isdst=-1) Time.struct_time (tm_year=2016, tm_mon=6, tm_mday=22, tm_hour=0, tm_min=0, tm_sec=0, tm_wday=2, tm_yday=174, tm_isdst=- 1)

Import time# Convert the struct time object to timestamp Struct_2_stamp = Time.mktime (string_2_struct) print (struct_2_stamp) input result: 1466524800.0

Import time# # return time format "Fri 11:14:16" a = Time.asctime (string_2_struct) print (a) input result: Wed June 22 00:00:00 2016

Import time# convert timestamp to string format print (Time.gmtime (Time.time ()-86640) # converts the UTC timestamp to the struct_time format to enter the result: Time.struct_time (tm_ year=2017, tm_mon=11, tm_mday=29, Tm_hour=8, tm_min=49, tm_sec=21, tm_wday=2, tm_yday=333, tm_isdst=0)

Import Timeprint (Time.strftime ("%y-%m-%d%h:%m:%s", Time.gmtime ()) # converts the UTC struct_time format to the specified string format print ( Time.strftime ("%y:%m:%d%h:%m:%s", Time.gmtime (Time.time () +28800)) # Eight zone time print ("\033[32m%s\033[0m"% time.strftime ("%y:%m:%d%h:%m:%s")) # positive Eight zone time print ("\033[31m%s\033[0m"% time.strftime ("%y-%m-%d%h:%m:%s", Time.localtime ()) # Eight zone time input result: 2017-11-30 08:53:212017:11:30 16:53:212017:11:30 16:53:212017-11-30 16:53:21
