To continue the wind back ...

In several implementations, reset_timer() actually reloads
or re-initializes the hardware timer. This has the effect of
synchronizing get_timer() calls with subsequent interrupts.
This prevents the early timeouts if the implementer chooses
to use an interrupt rate less than 1 ms.

So my original question was, how do we address this issue?
