Remote PowerShell, Local Variables, and ForEach - windows

Question

I am looking to get a file inventory of a specific file on some reomote servers using PowerShell and Invoke-Command. I want to gather the info and then export as CSV to a specific folder.
I have a couple of local variables for the date (to append to the file name) and a list of servers. I understand that I need to use the -ArgumentList parameter to pass the local variables, but the syntax is confounding me with the ForEach aspect involved (I am not a programatically minded person). Here is what I have:
$FileServerList = "Server01","Server02","Server03"
$DateTime = Get-Date -Format s
ForEach ($FileServer in $FileServerList) {
Invoke-Command -ComputerName $FileServer -ScriptBlock {
Get-ChildItem -Path "D:\PathtoFile\*" -Recurse -Include "index.html" | Select-Object Name,DirectoryName,CreationTime,LastWriteTime`
| Export-Csv -Path C:\Users\Public\Documents\Data_$DateTime.csv -NoTypeInformation -Verbose
}
}
Should I save the script block itself in a variable or go another route? Any guidance is appreciated.

Since Invoke-Command is not called with a separate credential, I assume that the user in current Powershell session has credentials to access servers.
For remote locations, you can use UNC paths:
$FileServerList = "Server01","Server02","Server03"
$DateTime = Get-Date -Format s
ForEach ($FileServer in $FileServerList) {
Get-ChildItem -Path "\\$FileServer\d$\PathtoFile\*" -Recurse -Include "index.html" |
Select-Object Name,DirectoryName,CreationTime,LastWriteTime |
Export-Csv -Path \\$FileServer\c$\Users\Public\Documents\Data_$DateTime.csv -NoTypeInformation -Verbose
}
