[timespan]$uptime = new-timespan -start 0 -end 0
$currenttime = get-date
$startupid = 6005
$shutdownid = 6006
$minutesinperiod = (24*60)*$numberofdays
$startingdate = (get-date -hour 00 -minute 00 -second 00).adddays(-$numberofdays)

write-debug "'$uptime $uptime" ; start-sleep -s 1
write-debug "'$currenttime $currenttime" ; start-sleep -s 1
write-debug "'$startingdate $startingdate" ; start-sleep -s 1

$events = get-eventlog -logname system | 
where-object { $_.eventid -eq  $startupid -or $_.eventid -eq $shutdownid `
  -and $_.timegenerated -ge $startingdate } 

write-debug "'$events $($events)" ; start-sleep -s 1

$sortedlist = new-object system.collections.sortedlist

foreach($event in $events)
{
 $sortedlist.add( $event.timegenerated, $event.eventid )
} #end foreach event
$uptime = $currenttime - $sortedlist.keys[$($sortedlist.keys.count-1)]
write-debug "current uptime $uptime"

for($item = $sortedlist.count-2 ; $item -ge 0 ; $item -- )
{ 
 write-debug "$item `t `t $($sortedlist.getbyindex($item)) `t `
   $($sortedlist.keys[$item])" 
 if($sortedlist.getbyindex($item) -eq $startupid)

mr raj not technician. posts here script has found people rewrite them him.

mr. raj.  when going learn how edit simple script.

mike shoed how enumerate file of names need learn how use call script.  cannot shoehorn example script , say it doesn't work.  error message clear. "param" statement see how used.

import-csv .\serverlist.csv | foreach {

     .\serveruptime.ps1 -computername $_.servername
}

now fix script has parameter computername.

param(
    $computername,
    $numberofdays = 30,
    [switch]$debug
)

the rest have muddle through.  time figure out have learned how write script.

i don't think mike wants rewrite you.
