To measure time with high precision, either use time.clock() or time.time() functions. The python docs state that this function should be used for benchmarking purposes.Exampleimport time t0= time.clock() print("Hello") t1 = time.clock() - t0 print("Time elapsed: ", t1 - t0) # CPU seconds elapsed (floating point)OutputThis will give the output −Time elapsed:  0.0009403145040156798Note that different systems will have different accuracy based on their internal clock setup (ticks per second). but it's generally at least under 20ms. Also note that clock returns different things on different platforms. On Unix, it returns the current processor time as a floating point number expressed ... Read More

In this article, we will look at different ways to get minutes, seconds, and milliseconds from datetime now in Python. The datetime.now() method is used to get the current minutes, seconds, and milliseconds. This is defined under the datetime module. Syntax The syntax of now() method is as follows − datetime.now() Returns the current date and time in time format. Using the datetime.now() and epoctime() Here we use the strftime() method which is provided by the datetime module. We have used the datetime.now() method to get the current date. Then we format this date by using the strftime() method. ... Read More

In this article, we will discuss the various way to retrieve the current time in milliseconds in python. Using time.time() method The time module in python provides various methods and functions related to time. Here we use the time.time() method to get the current CPU time in seconds. The time is calculated since the epoch. It returns a floating-point number expressed in seconds. And then, this value is multiplied by 1000 and rounded off with the round() function. NOTE : Epoch is the starting point of time and is platform-dependent. The epoch is January 1, 1970, 00:00:00 (UTC) on Windows ... Read More

You can use the pymongo library in Python to connect to a MongoDB database and use it to insert, update, delete, etc objects in Python. The library supports Python datetime objects out of the box and you dont need to do anything special to insert dates in Mongo using PyMongo.Examplefrom pymongo import MongoClient # This will try to connect to MongoDB on the default port and host client = MongoClient() db = client.test_database # Insert the given dictionary to the objects collection: result = db.objects.insert_one({"last_modified": datetime.datetime.utcnow()}) print("Object inserted!")OutputThis will give the output −Object inserted!Note − Always use datetime.datetime.utcnow(), which returns ...

You can use the fromtimestamp() function from the datetime module to get a date from a UNIX timestamp. This function takes the timestamp as input and returns the datetime object corresponding to the timestamp.  Exmaple import datetime timestamp = datetime.datetime.fromtimestamp(1500000000) print(timestamp.strftime('%Y-%m-%d %H:%M:%S'))OutputThis will give the output −2017-07-14 08:10:00

You can subtract a day from a Python date using the timedelta object. You need to create a timedelta object with the amount of time you want to subtract. Then subtract it from the date. Example from datetime import datetime from datetime import timedelta today = datetime.today() yesterday = today - timedelta(days=1) print(today) print() print(yesterday)OutputThis will give the output −2017-12-29 12:28:06.531791 2017-12-28 12:28:06.531791You can also subtract years, months, hours, etc. in the same way from a date using the timedelta object.

In this article, we will convert a python date format to 10-digit format for MySQL. We use the mktime() method from the time module provided by python. The mktime() method The python time method mktime() is the inverse function of the localtime(). The time.mktime() method of the Time module is used to convert a time.struct_time object or a tuple of 9 elements(which represents the time.struct_time object) to time in seconds since the epoch of the local system. Syntax The syntax of mktime() method is as follows. Time.mktime(t) Where, t is a time.struct_time object or a tuple containing 9 elements ... Read More

In this article, we will discuss how to convert a date to a datetime object in Python. We use the combine method from the datetime module to combine a date and time object to create a datetime object. Syntax The syntax of combine() method is as follows. datetime.combine(date, time) Where, date is a date object. time is a time object. This method returns a datetime object which is the combination of the above two objects (date, time). Converting a date object to datetime object If we have a date object and don't have a time object, then ... Read More

You can suspend the calling thread for a given time in Python using the sleep method from the time module. It accepts the number of seconds for which you want to put the calling thread on suspension for. Exampleimport time while(True):   print("Prints every 10 seconds")   time.sleep(10)OutputPrints every 10 seconds Prints every 10 seconds Prints every 10 seconds ...Each of the above statements will be printed every 10 seconds.Note that this method also supports floating point values so you can also put the calling thread to sleep for fractions of seconds.

Use time.clock() for timing/benchmarking if you need to choose between time and clock in Python.time() returns the the seconds since the epoch, in UTC, as a floating point number on all platforms. On Unix time.clock() measures the amount of CPU time that has been used by the current process, so it's no good for measuring elapsed time from some point in the past. On Windows it will measure wall-clock seconds elapsed since the first call to the function.Changing the system time affects time.time() but not time.clock().If you're timing the execution of a block of code for benchmarking/profiling purposes, you should ...
