Combine each element of the same line by multiple arrays

I have a script that extracts some values from a list of log files. Each value is inserted in an array.

At the end of the script I'd like to combine each line of each array and export them in an excel file.

Here is the script:

while (1) {
 clear
     $list = New-Object System.Collections.ArrayList
     $list2 = New-Object System.Collections.ArrayList
     $list3 = New-Object System.Collections.ArrayList
     $list4 = New-Object System.Collections.ArrayList
     $dir_to_look = "C:\test"
     $30_days_backdate=$(Get-Date).Adddays(-30) ####pour tester
     $contenu = Get-childitem $dir_to_look -recurse LOG20* |where { $_.lastwritetime -gt $30_days_backdate }| Get-Content   
 ############### Fichier log du jour

     foreach ($line in $contenu) {
         if ($line -match "CFTT82E.*IDT=(.+?)\b.*") {

                $str = $line.Split(' ') 
                $props = [ordered]@{    
                 Heure = $str[2] 
                 Date = $str[1]       ############ Heure où le message est apparu ######################
                                   }
        $heure_plantage=$str[2] 
         $date_du_plantage=$str[1]       


             $idt = $matches[1]
                 if(!$list.contains($idt)){
                     if ($line -match "CFTT82E.*PART=(.+?)\b.*") { ############### Récuperrer le nom_du_partner #################
                             $part = $matches[1] 

                                                                 }

                  $list.add($idt)
                  $list2.add($heure_plantage) 
                  $list3.add($part) 
                  $list4.add($date_du_plantage)
                  $conver=$list4 |Foreach-Object {$_ -replace "([0-9]+)/+([0-9]+)/+([0-9]+)", '$3-$2-$1'} # conversion date en EU 



           }
           }


     }
     ###visual test of the array values
     write-host "$list"
     write-host "$list2"
     write-host "$list3"
     write-host "$conver"

     break }

The output of these arrays is this (may contain more values in each line.I left only four values for the purpose of this question):

A1512201 A1512204 A1512203 A1512205 
12:20:06 12:20:08 12:20:16 12:20:25 
 TOTO      TITI     DPFDDFL PACKA
15-01-14 12-03-14 13-03-14 13-03-14 
So, I'd like to have the following output in the right order:
DATE      HOUR         IDT       PARTNER
15-01-14 12:20:06   A1812201      TOTO
12-03-14 12:20:08   B1212204      TITI
13-03-14 12:20:16   A1912203      DPFDDF
13-03-14 12:20:25   A2012205      PACKA
Any suggestion is welcome,
Thank you in advance.
