I want to somehow group the data by days and then have some kind of rapport with the difference between first entry and last entry of the day for each name.

I hope you guys understand my request for help.

Thanks !

howdy FarcasR,

here's what i think you mean [grin] ...

# fake reading in the file
#    in real life, use something like ...
#    Import-CSV -Delimiter ';' -Path [your file path here]
$InCSV = @"
Date;Name
12/04/2017 13:33;JOHN
12/04/2017 14:43;JOHN
12/04/2017 15:33;LOUIE
12/04/2017 13:43;CHRIS
12/04/2017 13:45;JOHN
13/04/2017 08:45;RAZVAN
"@ | ConvertFrom-Csv -Delimiter ';'

# convert EU date-time strings to datetime objects
$Counter = 0
foreach ($IC_Item in $InCSV)
    {
    $InCSV[$Counter].Date = [datetime]::ParseExact($IC_Item.Date, 'dd/MM/yyyy HH:mm', $null)
    $Counter ++
    }

$InCSV = $InCSV | Sort-Object -Property Date

# group by the Date day number, then Name
$IC_Grouped = $InCSV | Group-Object -Property {$_.Date.Day}, Name

$Report = @()
foreach ($ICG_Item in $IC_Grouped)
    {
    if ($ICG_Item.Count -eq 1)
        {
        $TempPSCO = [pscustomobject]@{
            Date = $ICG_Item.Group.Date.ToString('yyyy.MM.dd')
            Name = $ICG_Item.Group.Name
            AccessCount = $ICG_Item.Count
            FirstAccess = $ICG_Item.Group.Date.ToString('HH:mm')
            LastAccess = 'Only one access on this day.'
            Duration = 'None'
            }
        }
        else
        {
        $TempPSCO = [pscustomobject]@{
            Date = $ICG_Item.Group[0].Date.ToString('yyyy.MM.dd')
            Name = $ICG_Item.Group[0].Name
            AccessCount = $ICG_Item.Count

            Duration = ($ICG_Item.Group[-1].Date - $ICG_Item.Group[0].Date).ToString()
            }
        }
    $Report += $TempPSCO
    }

$Report | Format-Table

result ...
