How can THIS be a const, hmm?

Please replace the line with:
clock_t CLK_TCK(){ return cast(clock_t) sysconf(2); }

Using "static this" would work for common use-cases but not if
running applications are beeing migrated between different systems.

D's const isn't exactly Java's const ...

sounds good, but

My first instinct when I read that message was to post just such a 
reply, but then I noticed he wasn't talking about his own code. This is 
in Phobos's std.c.time module...
