Rob,
You keep saying this, but there's only one kind of clock and
one kind of time. When you get two or more clocks you have
the ability to compare them and measure time interval among
them. Time interval is often an integer (cycles) and fraction
(of cycles). What you are calling time of day is merely time
interval, where the start time is an artificial agreed upon point
in the past. But it's still all time interval.

No, there is time where different instances of the same nominal time
interval
in the same reference frame will have the same duration, measured with
atomic transitions or other physical
phenomenon, and "time" (actually, angular position of the Earth) where
different instances of the same
nominal "time" interval will have different durations when measured with
atomic transitions.
