Common time methods for Python

In Jython

Let's start by importing a module that must be used
>>> Import Time
Set a time format that will be used below
>>>isotimeformat= '%y-%m-%d%x '
Look at the current time, similar to many other languages this is the number of seconds since the epoch (January 1, 1970 00:00:00) to the current.
>>> Time.time ()
1180759620.859
I can't read the above, let's look at it in a different format.
>>> Time.localtime ()
(2007, 6, 2, 12, 47, 7, 5, 153, 0)
LocalTime returns the time in tuple format, a function similar to it is called gmtime (), the difference between 2 functions is the time zone, Gmtime () returns the value of 0 time zone, LocalTime returns the value of the current time zone.
>>> time.strftime (Isotimeformat, Time.localtime ())
' 2007-06-02 12:54:29′
With our time format defined, using Strftime to make a transition to time, if the time taken now, time.localtime () can not be used.

>>> time.strftime (Isotimeformat, Time.localtime (Time.time ()))
' 2007-06-02 12:54:31′
>>> time.strftime (Isotimeformat, Time.gmtime (Time.time ()))
' 2007-06-02 04:55:02′
The above shows the difference between Gmtime and localtime.
View time zone with
>>> Time.timezone
-28800
The above value is a second value, which is the description of the current time zone and the 0 time zone difference, -28800=-8*3600, which is the East eight zone.

A few simple functions

def isostring2time (s):
‘‘‘
Convert a ISO format time to second
from:2006-04-12 16:46:40 to:23123123
Turn a time into a second
‘‘‘
Return Time.strptime (S, Isotimeformat)
def time2isostring (s):
‘‘‘
Convert second to a ISO format time
from:23123123 to:2006-04-12 16:46:40
Converts a given second into a defined format
‘‘‘
Return Time.strftime (Isotimeformat, Time.localtime (float (s)))
def dateplustime (d, T):
‘‘‘
D=2006-04-12 16:46:40
T=2 hours
return 2006-04-12 18:46:40
To calculate the date of the number of seconds between a date, Time2sec is another function that can handle, 3 days, 13 minutes, 10 hours, and so on, to write this again, and to combine regular expressions.
‘‘‘
Return time2isostring (Time.mktime (Isostring2time (d)) +time2sec (t))
def datemindate (D1, D2):
‘‘‘
Minus to ISO format date,return seconds
Calculate the number of seconds between 2 time differences
‘‘‘
D1=isostring2time (D1)
D2=isostring2time (D2)
return Time.mktime (D1)-time.mktime (D2)
