I am trying to set up a short timer - 1 minute.
After creating the timer, I immediately start it, and it immediately displays a message that it's already over:

Do I have to enter a specific time (like an alarm - e.g. 10:30), or do I have to input a countdown period?
Sometimes even the time displayed in the timer is changed (just after I start it) - in this case, 19:20 -> 19:39 :
