Time does not just exist. That is correct. It is a human construct, like
all other things. We define it, as all other things, and then make useful
empirical comparative observations with it.

I think you might be missing the point, the OED definition that you
quote
does not define time itself as an absolute measurable entity, and what
time
nuts measure are, yet again, the intervals between events.
Define absolute measurable

Here's another way to look at it:
Time is what keeps things from happening all at once.
Also, without time there can be no motion (velocity, acceleration x time).
The units of distance are arbitrary - from the King's foot to a chosen
number of atomic wavelengths. And so the units of time are

That all depends on what your definition of is is :-)
If from relativity theory time is NOT
considered invariant, would frequency (in terms of the output of a cesium
standard or hydrogen maser)
be considered invariant?

I can not see how time is any different to any other quantity in
Maxwell's equations,
so time must be just as measurable, real and physical.

Hi Paul:
Glad to hear it's working!
Free schematic software at:
http://www.expresspcb.com/
They also have PCB layout that's tied to the schematic and very
reasonable prices for making boards.
No interest in the company other than being a happy user.
Have Fun,

There is at least one thing that you cannot do with time, which you can do
with pretty much everything else: you cannot go back and recheck your
measurement. ...

Yes, the whole PDP-11 line used line frequency to update the real-time
clock.
DEC had a real-time operating system, very useful for emulation of analog
process control functions. Of course, an RTOS is more than just the clock.
We lost that anchor to real time in the interval between the PDP-11
