$allowedDifferenceSeconds = 20

$VCServerName = "xxxxxxxxx"

$VC = Connect-VIServer $VCServerName

$TimeStamp = Get-Date -format "yyyyMMdd-HH.mm"

$Csvfile = "c:\temp\$VCServerName-HostDateQuery.csv"

$HostDateQuery = @()

get-view -ViewType HostSystem -Property Name, ConfigManager.DateTimeSystem | %{   

    #get host datetime system

    $dts = get-view $_.ConfigManager.DateTimeSystem

    #get host time

    $t = $dts.QueryDateTime()

    #calculate time difference in seconds

    $s = ( $t - [DateTime]::UtcNow).TotalSeconds

    #check if time difference is too much

    if([math]::abs($s) -gt $allowedDifferenceSeconds){

        #print host and time difference in seconds

        $row = "" | select HostName, Seconds

        $row.HostName = $_.Name

        $row.Seconds = $s

        $row

        $HostDateQuery += $row
