Linux date now minus minutes5/9/2023 ![]() It can be the combination of any one of the following: $ file, please wait." # rest of script # tar xcvf /nas42/backup.$ /home/ /etc/ /var A complete list of FORMAT control characters supported by the GNU/date command $" echo "Backing up data to /nas42/backup. To display a variable use the following simple commands to output on screen under Linux and UNIX using the printf command/ echo command: Simply type the following command at the shell prompt to get the current date in MM-DD-YYYY format: Sample outputs: 00-50 How do I save time/date format to the shell variable? To display locale’s 12-hour clock time, enter: Open a terminal and type the following date command: The following examples are tested on GNU/Linux, Apple OS X Unix, and FreeBSD unix operating system. The syntax is as follows for the GNU/date and BSD/date command:Īn operand with a leading plus ( +) sign signals a user-defined format string which specifies the format in which to display the date and time. Basically, you need to convert them into datetime object first and then calculate their difference.Linux Syntax To Format Date For Display On Screen So you can use the above approach to calculate datetime difference between date strings, datetime-based database columns, or simply datetime information available as numbers. Most python libraries for database connection return a datetime database column as datetime object. You can also use them to calculate date/time difference between results of database queries. In this article, we have learnt how to easily create date, time, datetime objects in python and use them calculate time difference in days, hours, minutes & seconds. For that, you will need to divide the above time difference in seconds, by 60 for minutes and 3600 for hours. print(tdelta.total_seconds())ĭatetime module does not provide functions and attributes to get time difference in minutes & hours. ![]() If you want to get the entire time difference as seconds, use total_seconds() function. It will convert the time part of your timedelta (hh:mm:ss) into seconds. Similarly, if you want time difference in number of seconds, you just need to use seconds attribute of timedelta object. Here is an example to get number of days between the above two dates. If you only want to get number of days in time difference, use the days attribute of timedelta object. Timedelta object is useful as it has many pre-built attributes and functions to quickly derive specific information as per your requirement.įor example, as you can see, the timedelta gives time difference in days, hours, minutes, and seconds. If the above code gives an error on your Python( So this returns a very intuitive time difference value. > import datetimeĪs you can see, datetime returns the time difference in HH:MM:SS format, instead of returning total number of seconds, as done in Linux/MySQL. You just need to store current time in a variable, wait for a while, store current time in another variable, and get the difference between both variables. Now that you can create a datetime object, here is a simple example to calculate time difference. Here is a simple example to import datetime module into your code and get a datetime object that points to current time. datetime module allows you to create date, time, or datetime objects, as per your requirement, to calculate time difference. It allows you to easily create datetime objects required to calculate time difference. Most developers use the default datetime module that is already pre-installed in python. How to Calculate Time Difference in Python ![]() In this article, we will learn how to calculate time difference in Python. Often Python developers might need to calculate time difference in python, to use it in their application/website, or simply to measure execution time.
