oooo, maybe that's the bug.  If it really is a global variable and this is a 
threaded server, it's likely to break.  We need a variable that's unique to the 
request.  Probably the cleanest way to do that is introduce a new time parm to 
the functions called by do_cadget which need it.

I'll whip something like this up unless someone beats me to it.
