Hi All.
Apart from this already making a WikiPedia standard - what is the
consensus - change the name or just update the documentation?
Looking at the names again it seems that the units aren't the same
either. T32kHz implies 1/s and TMilli implies well ~ms. So it might make
sense to keep the unit the same too.
And what about 32kHz - is it implicitly clear that this is 32768 Hz?

Judging from the changes this user has made it could be one of the
MoteIV guys with a desire to play board games =].

The post offers alternative namings, which avert having to come up with
new standards - which was the problem in the first place:
TkibiHz, TmebiHz
Of course this takes out the fun in arguing, over who was the first
human to use the term milbi =].
