Allow positive steps only once per second for as much as one second, but no more. Allows a miscreant to double-time march the clock, but no worse. XXX Unlike putting negative deltas in a while(1), performing small positive steps inside of a while(1) will return EPERM for the unpermitted ones. Repeated negative deltas are clamped without error (but the kernel does log a notice). END
