In PowerShell, how do I convert DateTime to UNIX time?

In PowerShell, how can I convert string of DateTime to sum of seconds?

Solution 
  • PS H:\> (New-TimeSpan -Start $date1 -End $date2).TotalSeconds

1289923177.87462

    New-TimeSpan can be used to do that. For example,

    $date1 = Get-Date -Date "01/01/1970"
$date2 = Get-Date
(New-TimeSpan -Start $date1 -End $date2).TotalSeconds

    Or just use this one line command

    (New-TimeSpan -Start (Get-Date "01/01/1970") -End (Get-Date)).TotalSeconds
