How to create a dynamic variable in Powershell, sucha as date/time etc

Question

Hi i am not exactly sure if my wording is right but i need a variable which contains current date/time whenever i write data to log ; how can i do that with

Answer 1

Why not use:

Add-Content $LogFile -Value "$((Get-Date).DateTime): XXXXX"

This gets the current datetime every time. Notice that it's inside $( ) which makes powershell run the expression(get the datetime) before inserting it into the string.
