Perhaps this is what you want?

```julia
julia> a = Dates.DateTime(2017,11,18):Dates.Second(29):Dates.DateTime(2017,11,19)
2017-11-18T00:00:00:29 seconds:2017-11-18T23:59:51

julia> collect(a)
2980-element Array{DateTime,1}:
 2017-11-18T00:00:00
 ⋮                  
 2017-11-18T23:59:22
 2017-11-18T23:59:51

julia> ceil.(collect(a), Dates.Minute(1))
2980-element Array{DateTime,1}:
 2017-11-18T00:00:00
 ⋮                  
 2017-11-18T23:58:00
 2017-11-18T23:59:00
 2017-11-18T23:59:00

On Julia 5.0 not works… Do you try it on Julia 6.0 ?
