Hello,
I found this problem when I tried using `Dates.Time` as dictionary keys:
```julia
julia> a = Dates.Time(0)
00:00:00
julia> b = Dates.Time(0) + Dates.Hour(24)
00:00:00
julia> a == b
true
julia> isequal(a, b)
true
julia> hash(a) == hash(b)
false
```
Documentation says that `isequal(x, y)` should imply `hash(x) == hash(y)` so I think this needs to be fixed.
Am I correct? Should I open an issue (or PR) on Github?

Good catch, please file an issue!
FWIW:
```julia
julia> dump(a)
Time
instant: Nanosecond
value: Int64 0
julia> dump(b)
Time
instant: Nanosecond
value: Int64 86400000000000
```
