The end instance is already implemented.  Why change it now?

You have two choices:

1. invent a new clock_type with its own .c and .h file
2. adapt one of the existing clock_types

The correct choice depends on the nature of the changes needed.  On
the one hand, if all that is needed is a one-liner, then #2 is the
obvious choice.  On the other hand, if the changes mean sprinkling

    if (my_special_case) { do_my_special_stuff(); }

everywhere, then #1 makes sense.

In any case, it is hard to guess without seeing your code.  Why not
post what you have done already as an RFC?
