AlarmManager problems when changing the system clock

I have a service that updates some data every minute. When I change the system clock of the phone or 开发者_如何转开发the emulator, the timer executes immediately n times with no delay between them.

Let's suppose that it is 10:00 pm. If I change the time to 11:00pm, the timer runs 60 times one by one with no delay between each run. My service generates HTTP requests so it'll trigger 60 request one by one for 4-5 secs.

What is wrong? I have got the same issue with the AlarmManager too. How can I prevent this behavior?

There is an issue for this
