Invalid DateTime

$tmpCreated = dir | Sort CreationTime -Descending | Select CreationTime -First 1 
    $tmpCreated = [string]$tmpCreated
    $tmpCreated = $tmpCreated.split("=")[1]
    $tmpCreated = $tmpCreated.split("}")[0]

Here is the variable I want to get as a DateTime. I want to compare two dates with this command :

$timeDiff = new-timespan –Start $tmpLast –End $tmpCreated

$tmpLast works fine. But I get an error when i try to launch, saying the -End parameter cannot be used because the $tmpCreated conversion failed. But here is the string it contains : 11/30/2015 11:57:01. So, does someone know what's wrong with this ?

The CreationTime property already contains a DateTime object, so you simply need to expand the property:

$tmpCreated = Get-ChildItem |
              Sort-Object CreationTime -Descending |
              Select-Object -Expand CreationTime -First 1

$timeDiff = New-TimeSpan –Start $tmpLast –End $tmpCreated

You don't need to convert the date to a string to use it with New-TimeSpan

$tmpCreated = dir | Sort CreationTime -Descending | Select CreationTime -First 1
$timeDiff = new-timespan –Start $tmpLast –End $tmpCreated.CreationTime

will do fine.
