Date and Time can be directly concatenated by "&" operator; thus, create a series of hours by List.Times,

 

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMjIwMtQ1ACGlWB0krpFSbCwA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Date = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Date", type date}}),
    #"Added Times" = Table.AddColumn(#"Changed Type", "Time", each List.Times(#time(0, 0, 0), 24, #duration(0, 1, 0, 0))),
    #"Expanded Custom" = Table.ExpandListColumn(#"Added Times", "Time"),
    #"Concatenated DateTime" = Table.AddColumn(#"Expanded Custom", "DateTime", each [Date] & [Time])
in
    #"Concatenated DateTime"
