Duplicate dates

You might want to include Timestamps inside your array that share the same timestamp:

julia> deja = Timestamp(Date(2000,1,3), 12)
2000-01-04 | 12

julia> vu = Timestamp(Date(2000,1,3), "twelve")
2000-01-03 | twelve

julia> vcat(clstamp, deja, vu)
502-element Array{Timestamps.Timestamp{T},1}:
2000-01-03 | 111.94
2000-01-04 | 102.5
2000-01-05 | 104.0
2000-01-06 | 95.0
2000-01-07 | 99.5
2000-01-10 | 97.75
2000-01-11 | 92.75
⋮
2001-12-24 | 21.36
2001-12-26 | 21.49
2001-12-27 | 22.07
2001-12-28 | 22.43
2001-12-31 | 21.9
2000-01-03 | 12
2000-01-03 | twelve

Notice that not only do you have three diffferent values for a single date, the ordering was not enforced.
