Transform lastLogon into date in power query

Hello Anonymous 

 

you need to devide and subtract something of the lastlogon-number in order to transform it to a DateTimeZone.

each DateTimeZone.From([lastLogon]/ 864000000000 - 109205)

 

Here a complete example

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMtQxNjQ2tnTVNjRXitWB8o3M4fy80pwchIS5OYpCQwNDVL4FqkGGplgMQjbRyMTUGFkH6XwTIzS+BZp6IwLmEZLHzzc0pK55hP2L7j+S9BsamVjiiRGscWRoaGmCPTkgmU3QrFgA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [lastLogon = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"lastLogon", Int64.Type}}),
    #"Added Custom" = Table.AddColumn(#"Changed Type", "Custom", each DateTimeZone.From([lastLogon]/ 864000000000 - 109205))
in
    #"Added Custom"

 

Copy paste this code to the advanced editor in a new blank query to see how the solution works.
