AD LastLogon format date

I have a powershell script that extracts lastlogon across my domain.

The relevant portion of script is:-

 $time=$currentUser.LastLogon

$dt=[DateTime]::FromFileTime($time)

The output is in us format I think (eg

however, I would like the date in uk format.

I understand the the culture can help, but I've not been able to get this to work with the above.

Any help, most appreciated.

Regards
