How to get Dates.Period without label?

General Usage
8

Huh, I didn’t know it could do this until I tried.

julia> x = Dates.canonicalize(Dates.CompoundPeriod(t2-t1))
17 minutes, 18 seconds, 522 milliseconds

julia> x.periods
3-element Array{Base.Dates.Period,1}:
 17 minutes      
 18 seconds      
 522 milliseconds

julia> x.periods[2]
18 seconds

julia> x.periods[2].value
18
