Sleep notifications wrong after summer time change

Detailed description of the problem:

After changing summer time settings, sleep reminder notifications is wrong about an hour. Details below.

Steps to reproduce:

  1. Make sure it is summer time
  2. Set your optimal sleep duration to 7 hours 30 minutes
  3. enable reminder to go to sleep.
  4. Set alarm time to 06:30
  5. Sleep reminder comes up at 23:00. All is okay.
  6. Wait until the phone changes to normal time again, that is switching from 03:00 to 02:00 automatically.
  7. The sleep reminder will come up at 22:00 now, which makes your sleep duration last 08 hours and 30 minutes. So either i will get too much sleep or have to remind myself to go to sleep manually. Both makes the reminder useless.

Version of Sleep as Android:
