Test case:

    import std.datetime;
    const SysTime a;
    SysTime b = a;

Error: cannot implicitly convert expression (a) of type const(SysTime) to
SysTime

This is extremely surprising to me, as I would expect SysTime to have value
semantics.  I suppose this has to do with the timezone field?

If this problem is unavoidable, I think that SysTime should either have a
copy/dup method, or at the very least it should be noted in the documentation
whether it is safe to cast it to mutable.
