[phobos] FreeBSD 32 still fails unittests for std.datetime

[Walter Bright]

I see you're using "class Clock" as a namespace. Defining a class creates a 
bunch of static data, like the vtbl[] for it. Better to make it a struct. But 
that still generates TypeInfo.

Even better to just call the functions with a common prefix, which you already 
do, i.e. "curr". Then there's no overhead bloat.
