从有效日期开始计算AD密码的年龄

Question

I want to calculate the age of the password, in days, using the PasswordLastSet property. I've created the below code but Password Age never outputs anything. I'm guessing there is a type error but I'm not sure how to convert to DateTime. Any thoughts?

Get-ADComputer myComputer -Properties PasswordLastSet | Select-Object -Property PasswordLastSet, @{Name = 'Password Age';Expression = {Get-Date - ([datetime]($_.PasswordLastSet))}}

Answer 1

The reason for the failure is the lack of parens around the Get-Date call. Without those parens, the cmdlet tries to use the remainder of the line as input ... [ grin ] wrapping the cmdlet in parens - (Get-Date) - forces the cmdlet to run without trying to parse the remainder of the line.
