How to sort values within one column by dates within another?

• Convert your two strings into Lists
• Convert each item in the date time string list into a datetimezone data type
• Zip the two lists together
• Sort by the second item in each zipped list
• Return the first items in the zipped list, combined with the comma delimiter

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("TY5LCsQwDEOvErJ2wPInJT5HVi29/zXG6XQ6BYNBtqR3HBVUjAq8UhUWa9ybbBMaPsL6TiVVbyxNfALBPVQeFQ06wcEjWPZ60lHHN8ivIP4HXUensv2KkOYxBWEI3EWpcs4q0hF+u5hKDiTXQ+kNybPF+tSXmZNdAh6mb0rMRFQL80fNBFnsWZ+/9Tw/", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Column1 = _t, Column2 = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Column1", type text}, {"Column2", type text}}),

    #"Add Sorted Column" = Table.AddColumn(#"Changed Type", "Sorted", (r)=>
        [a=Text.Split(r[Column1],","),
        b=Text.Split(r[Column2],","),
        c=List.Transform(b, each DateTimeZone.From(_)),
        d=List.Zip({a,c}),
        e=List.Sort(d, each _{1}),
        f=List.Transform(e, each _{0}),
        g=Text.Combine(f,",")][g], type text)
in
    #"Add Sorted Column"
