Thus, the article covered in detail in the various date time formats along with examples. The best way to learn about each format available is to try out each format and understand which is suitable for the script need. You’ll C++ Data Types Top 3 Most Useful Different Data Types of C++ see as soon as you use the Format parameter, Get-Date no longer returns a DateTime object but now strings a string. Use the New-TimeSpan cmdlet by providing a Start and End date/time as parameters.

When you do this, PowerShell tries to interpret the string as a date and time then provides you with all of the properties and methods available on this object type. With Get-Date we can get the current date and time which is often used in PowerShell scripts to timestamp the output or in combination with logging. But besides timestamping, we can also use dates to compare or calculate the age of files, or in filters to select only a specific range from a result set. The System.DateTime object that PowerShell Get Date command returns has various methods you can invoke to add or remove chunks of time. If you run Get-Date | Get-Member, you’ll see various methods that start with Add.
Since we know that the Get-Date command outputs a DateTime object, is there more that we can do with this object?

The UFormat parameter is similar to the Format parameter in that you can combine date format characters to change how the date is returned as a string. For example, try out the following formats and see what’s returned. Now that you are aware of the basic methods of using dates, it’s time to delve deeper into the topic.
