OK, but I'm not sure it's worth it. After all, that's the way it's working... Maybe there can be something to be done regarding the way you setup alarm: if user specifies a time, then it should be compatible with the period. But user may also not specify a time and just deal with period. More, if period is 10 seconds, then time specification is only "ss", not "ssmmhh". Maybe, to be explicit, user could specify "17FFFF", meaning "@ 17 seconds, whatver the minutes and hours are" ? The trouble is I'm not sure if you can issue warnings/errors at compile time for these. That's why it may not worth it... > Shouldn't 'repeat' be read as 'number of times after the first time'? To me > that seems normal.

Rechecked again, it works. Carefull I'm using 16Mhz Xtal running PLL. I think your setup is different regarding this.
