You can be pretty sure that I will NAK any design that _prevents_ me
from doing this when I have specific reasons to do exactly this or
something similar.
It is definitely a good idea to provide simple and reliable ways for
standard tasks - but you also must provide the freedom to do things
differently when the standard way does not fit for a reason or
another.
This is also why I consider it mandatory that get_timer() (or
time_read() or whatever it is going t be called) uses a standard unit
of time like milliseconds, and not som random internal scaling.
Best regards,
Wolfgang Denk
