I thought this would be easy but I can’t do it.  
I have a point of time in a day, say 9:15. I want to add time to this like 1.5  
How do I do that?

```julia
julia> using Base.Dates

julia> t = Time(9, 15)
09:15:00

julia> t + Hour(1) + Minute(30)
10:45:10

Extremely weird. I can’t reproduce it:

```julia
julia> Time(9,15) + Hour(1) + Minute(30)
10:45:00

julia> versioninfo()
