Windows has long had its own built-in NTP client. All you have to do
is use that. You can change the parameters as needed (I always point
the built-in client to my local NTP server and set the update
frequency to once every few minutes, given the poor accuracy of PC
clocks).

UTC is monotonic. The problem is with people who assume that minutes
always have 60 seconds. In UTC, they don't - they can have 59, 60, or 61

Apparently, in current versions of Windows, it is a home-cooked

within a very small fraction of a second while synchronizing from my

It is accurate enough that I can't see or hear a difference between

Of course, others can do as they wish, but why install something
special if the built-in client does well enough? I used to have

discovered that the regular client did just as well for my purposes, I
removed it.

The intel 64 bit CPUs used the AMD64 instruction set.
Note there are more instructions in the 64bit architecture, so some programs
are more efficient under a 64 bit OS.

That can be true. But NTP uses so little resources that that is very
little to be gained. But if you do care about this the best and
simplest solution (maybe the only solution)

What I've seen is that holding 0.1 C AT the SENSOR is pretty easy,
(Lady Heather will hold the TBolt's sensor to 0.01 deg using just a fan),
AND if you blow a lot of air around, then keeping the air gradients inside a
closed 'oven box' below 0.1 deg is also NO problem.

You have answered a couple of questions for me. The heat sink inside is
