I have used the planner in my local time zone and it worked pretty well. But the first time we planned a trip from Central to Eastern time zone and had to pick up a person at the airport was when we found out the planner did not account for time change. We were late in picking up the person by 1 hour. Since then, we have travelled through all 4 time zones in the lower 48 states. We still have to remind ourselves that trip planning and ETA needs mental calculation and adjustments. We sometimes bounce between navigation apps to check time and ETA to verify Waze ETA. At least now, no more Daylight Savings Time to worry about.
