Last night we change hour for daylight saving time (at 2:00 it would be 3:00).
So I made a simple test to set an alarm at 2:10
- At 1:59, clock jumped logically to 3:00
- no alarm
- At 3:10, alarm rang (in fact I had turned it off and back on, but that has no influence)
- I set an alarm at 3:15, of course it rang
- I set a new alarm at 2:20
- It rang at 3:20
Conclusion: Clock app "replicates" the alarms between 2:00 and 2:59 into 3:00 - 3:59.
Which is great, not to miss any.
Question: Is this specific to Clock app or a more general system behaviour for all time events ?
If so, there may be a side effect:
- I set an event A to turn On a light at 2:45
- And set event B to turn it Off at 3:15
- Then B will occur before A and the light will remain On
There is no perfect solution ("warping" 2:00 - 2:59 into a minute at 3:00 would creates other issues).
Extra question: What happens on winter time ? Will alarm ring twice at 2:10 ?
