Mark your setTime as shared, then cast away shared (as you don't need

I know I can make it work by casting, my question is:
we had a lock on the owning shared object already, WHY we still need the
cast to make it compile.
Because locking isn't that simple. There is no "one size fits all"
locking scheme that can be enforced by the language. So the best option
is to make sure if you shoot yourself in the foot, it's your fault, and
not D's.
