Failing in batch powershell

I have a powershell command that runs fine.

$(Get-Item c:1.txt).lastwritetime=$(Get-Date "01/22/2002 11:11 am")

I'd like to use it multiple time. Using a batch file. Before the batch file I used this:

Set-ExecutionPolicy Unrestricted

The batch contains commands like this one:

powershell -Command "$(Get-Item c:1.txt).lastwritetime=$(Get-Date "01/22/2003 11:11 am")"

The batch file fails, I got two error messages per command:

Get-Date : A positional parameter cannot be found that accepts argument '11:11'.

At line:1 char:49

+ $(Get-Item c:1.txt).lastwritetime=$(Get-Date <<<<  01/22/2003 11:11 am)

    + CategoryInfo          : InvalidArgument: (:) [Get-Date], ParameterBindingException

    + FullyQualifiedErrorId : PositionalParameterNotFound,Microsoft.PowerShell.Commands.GetDateCommand



Exception setting "LastWriteTime": "Cannot convert null to type "System.DateTime"."

At line:1 char:25

+ $(Get-Item c:1.txt). <<<< lastwritetime=$(Get-Date 01/22/2003 11:11 am)

    + CategoryInfo          : InvalidOperation: (:) , RuntimeException

    + FullyQualifiedErrorId : PropertyAssignmentException

Unfortunately I don't know what is wrong. Can some help me out?

You need to either escape the inner double quotes with a backslash (because cmd would see the date time unquoted)

powershell -Command "(Get-Item .1.txt).lastwritetime=(Get-Date "01/22/2003 11:11 am")"

or exchange the inner double with single quotes (as DavidPostill suggested).

powershell -Command "(Get-Item .1.txt).lastwritetime=(Get-Date '01/22/2003 11:11 am')"

Also the $ are only neccessary when forcing the expression inside a string.
