#requires -Version 7.3

# this rewrites the objects on the pipeline so that DateTime members are replaced with a string representation including milliseconds
# to work around the fact Export-CSV doesn't include milliseconds (see https://github.com/PowerShell/PowerShell/issues/19536)

# compute millisecond-aware version of the current datetime format
$format = "{0:" + (Get-Culture).DateTimeFormat.ShortDatePattern + ' ' + (Get-Culture).DateTimeFormat.LongTimePattern + '.fff' + "}"

foreach ($object in $input)
{
    # preserve order of properties
    $properties = $object.PSObject.Properties.Name

    $newobject = [PSCustomObject]@{
    }
    # convert all members that are timestamps to strings with milliseconds
    $object | Get-Member -MemberType NoteProperty | Foreach-Object {
        $member = $_
        if ($member.Definition -match '^System\.DateTime\s+') 
        {
            Add-Member -InputObject $newobject -MemberType $member.MemberType -Name $member.Name -Value ($format -f $object.($member.Name))
        }
        else
        {
            Add-Member -InputObject $newobject -MemberType $member.MemberType -Name $member.Name -Value $object.($member.Name)
        }
    }
