"""
@property @trusted long currStdTime(ClockType clockType = 
ClockType.normal)();
Returns the number of hnsecs since midnight, January 1st, 1 A.D. 
for the current time.

This choice of offset seems Esperanto-like: deliberately chosen 
to equally inconvenience every user. Is there any advantage to 
this at all on any platform, or is it just pure badness?
