I understand that rtems_clock_tick() will also handle all the
task switching etc. Is this correct?

No, of course not. I noticed that wrong number, too, as usual
shortly after the e-mail had been sent, but did not bother to
send a correction afterwards, as the frequency was not the main
issue here. Thanks anyway for pointing it out.

Kind regards
