The first thing I did was to read the documentation.
The 2.0 Source code documentation link on page
http://www.tinyos.net/tinyos-2.x/doc/ is broken, it points to
http://www.tinyos.net/tinyos-2.x/doc/html/nesdoc/ which gets a 404 error.
The 2.0 TEP is quite clear, I never got there. The 2.0

My apologies for the initial mis-send.

The timer system in TinyOS does not guarantee any particular accuracy, only
that accuracy MUST remain reasonable, probably something like +/-10% of
the declared units. This is for various reasons including but not limited
to temperature, voltage, and manufacturing variations that affect hardware

Of course the device capable for some definition

For time counts driven by a crystal the types of errors you are
talking about should result in time variations of seconds per day.
What I am seeing is seconds per minute.
A repeating counter set to 1000 milliseconds should count seconds
This seems to work much better. Where will I find it documented?

I was definitely led astray by the introductory material and the

such as Blink where 1000 milliseconds is used as a timer argument

It does fire every 1000ms. Every 1000 binary milliseconds to be precise.
