So here’s a little nugget that might help you at the end of backup sessions, or in my case, to adjust for the time zone difference on my vacation after forgetting to check my cameras clock for the entire 2 week duration. Despite it’s simplicity, this script is in fact quite powerful, and if used towards the wrong folder, or with the wrong scope (Get-Childitem -recurse) it can cause a bit of damage.
A fun thing about this script is that by changing the time parameter, you can actually put the Date Modified field into the future without changing the clock on your computer
