That is only your recommend, not mean I have duty to.

At least before say so, please reply:

If we assume "If there is nothing in tv2 which might come before the
found timer, then any timer in tv3 will ..." is correct.

When we found a timer in 'tv1', we will not search all timers in 'tv2'
(we only search first looping of tv2 for the specific 'slot').

Is it still OK ?

If you do not want to discuss with others, better quite politely, not
need judging or checking others, it is useless for the cooperation with
each other, is it right ?  ;-)


Thanks.
