    Sure (I included some Dutch as well :-) ):

     

    let
    Source = #table(type table[Verwachte_Start = text],{{"1499032800"},{"1498860000"},{"1493589600"},{"1491170400"}}),
    AddedUTCDateTime = Table.AddColumn(Source, "Verwachte_startdatum/tijd_UTC", each #datetimezone(1970,1,1,0,0,0,0,0) + #duration(0,0,0,Number.From([Verwachte_Start])), type datetimezone),
    AddedLocalDate = Table.AddColumn(AddedUTCDateTime, "Verwachte_startdatum_lokaal", each Date.From([#"Verwachte_startdatum/tijd_UTC"]), type date)
in

Hi MarcelBeug, 

 

Thank you for your solution, you're great!

I also learned that an alternative to this is: 

1. Convert the text to a number by the following formula (creat new column) : Verwachte start number = value([verwachte_start] )/(60*60*24) 

2. Convert the value to a year date format (create new column) : Verwachte StartJaar = YEAR(IF([Verwachte start number] = BLANK() ;BLANK();DATEVALUE("01/01/1970") + [Verwachte start number])) 

 

Cheers,
