[Bug 1512180] [NEW] Standard alarms will not work correctly for Timers, after timezone/DST change

 

Public bug reported:

Standard alarms will not work correctly after changing timezone and
during DST change.

Steps to reproduce:
1. Install Timer from Store: https://uappexplorer.com/app/timer.mivoligo
2. Set timer to 5 minutes
3. Open Clock app. Look for alarm, and notice that alarm is correctly set
3. Switch to System Settings -> Time & Date -> Time zone:
4.  Change Time zone to something different (eg. New York). (Or wait for DST change: https://en.wikipedia.org/wiki/Daylight_saving_time)

Expected behaviour:
- timer ringing as expected after timezone/DST change

Current behaviour:
- alarm is not ringing. (you could check active alarms in "Ubuntu Clock app)

Proposal solution:
- introduce new type of alarms, which is based on UTC (https://en.wikipedia.org/wiki/Coordinated_Universal_Time) and independent from time zones.
