Hmm, this isn't quite right because Time internal values aren't normalized down; i.e. Dates.value(Time(0,0,0)) != Dates.value(Time(0,0,0) + Dates.Hour(24)). I would maybe just mirror the definition of +(d::Date, t::Time) here

If I define it as DateTime(UTM(value(d) * 86400000 + (value(t) / 1000000) % 86400000)),
seems works.
There are no significant performance differences between mine and +, so I mirrored the +(d::Date, t::Time).

It seems a bit backwards to me to have something in types.jl depend on something arithmetic.jl; would you mind switching the definitions around? i.e. have types.jl define the actual definition and then change the arithmetic.jl definition to just call DateTime(dt, t)? It might just save some headache down the road if further refactoring is done (keeping the dependency graph clean and all that...)
