how to use powershell to copy file and retain original timestamp

I would like to copy some files or a folder of files from one file server to another. However, I want to keep the original timestamp and file attributes so that the newly copied files will have the same timestamp of the original files. Thanks in advance on any answer.

Here's a powershell function that'll do what you're asking... It does absolutely no sanity checking, so caveat emptor...

function Copy-FileWithTimestamp {
[cmdletbinding()]
param(
    [Parameter(Mandatory=$true,Position=0)][string]$Path,
    [Parameter(Mandatory=$true,Position=1)][string]$Destination
)

    $origLastWriteTime = ( Get-ChildItem $Path ).LastWriteTime
    Copy-Item -Path $Path -Destination $Destination
    (Get-ChildItem $Destination).LastWriteTime = $origLastWriteTime
}

Once you've run loaded that, you can do something like:

Copy-FileWithTimestamp foo bar

(you can also name it something shorter, but with tab completion, not that big of a deal...)
