TimeAlarms Questions.

Hi,

I have several questions for using TimeAlarms Library. I am using it with ESP8266. Time Update is using NTP or Manual Update.

Alarm.alarmRepeat(8,30,0, MorningAlarm);

A) Does it fires exactly at 8:30am, whats the flexibility in difference in time? I mean Lets say loop was busy in some other function and Alarm.delay was called at 8:31am will it trigger alarm function or will it skip?

B) Can we adjust Time inside Alarm Function? Like adjusting DST time at particular UTC time?

C)
As far as I understand by reading details is that if time is changed it affects timing of Alarm.
So we need to reschedule the alarms again after changing time.

D) Any other alternative library available for scheduling Alarm Functions?

I am still a learner so please bear with me.

Thanks for help.

It will trigger the alarm function.

Theoretically yes, but you have to check for race conditions.

No, but you might have to call updateNextTrigger() on the stored Alarms to ensure they get called correctly.
