datetime - Powershell date comparison not returning expected results -

Not sure I'm doing something wrong but I hope that the result is not being found.

To return a UTC date / time value, then I can request both local and remote machines to have the following functions

  Function Get-UTCTime {Ultimate ([String] $ computername = $ env .: computername) $ UTC = get- WmiObject win32_utctime -ComputerName $ computername return $ sysdt = ([string] $ utc.month + "/" + [string] $ utc.day + "/ [+ [String] $ utc.year +" "+ [string] $ utc.hour +": "+ [string] $ utc.minute +": "+ [string] $ utc.second)} [datetime ] $ Lsysdt = Get- UTCTime "". Type Host "Local:" $ lsysdt [datetime] $ rsysdt = Get- UTCTime $ Computer Write-Off "Remote:" $ rsysdt.addminutes (6) $ tester1 = $ lsysdt - $ rsysdt $ tester2 = New-TimeSpan -Start $ Lsysdt end $ rsysdt type host "tester1" $ tester1 type host "tester2" $ tester2   
 My results are as follows  
  Local: 6 / 21/2013 6:06:43 PM Remote: 6/21/2013 6:12:45 PM Examiner 1 -00: 00: 02 Examiner 2 00:00:02   
 You You can see that I have 6 minutes and 2 second difference in time, but the resultant value is only Identifies Ekand.  
 I have expanded all properties on tester1 variable and still do not see that it contains minutes.  
  Ticks: -20000000 Days: 0 hours: 0 milliseconds: 0 minutes: 0 seconds: -2 TotalDays: -2.31481481481481E-05 TotalHours: -00555555555555556 TotalMilliseconds: -2000 TotalMinutes: -. 0333333333333333 TotalSeconds: -2   
 What is the simple low concept I am missing with Datetime Comparison?
