DailyPlan - Fix parsing issue with non-existent local times during DST transitions

Current Situation

• For time zones that make use of Daylight Saving Time (DST), there is a switch-over period during which the clock is forwarded (frequenlty from 2am to 3am) for summertime and back (frequently from 3am to 2am) to introduce wintertime.
• If a user schedules an order for a time that meets the switch-over period (between 2am and 02:59:59), then this fails as this hour does not exist for that day due to forwarding of the clock.

Desired Behavior

• During summertime switch-over orders are created by the Daily Plan Service to the later hour, for example to 3.30am instead of 2.30am (as the time does no exist for that day.)
• During wintertime switch-over orders are not duplicated when the clock is moved back, for example from 3am to 2am.
