Waze should show ETA and arrival time in the destination's local time zone, not the phone's current zone.
Why it matters: On a Stevensville, MI (Eastern) → Great Lakes / Chicago (Central) drive, Waze showed arrival an hour late until the phone flipped zones. That breaks appointment planning when the destination is in another zone.
How to implement (practical path):
At route start (and whenever the destination TZ differs from the device TZ), look up the destination's IANA time zone (same data Apple Maps / Google Maps already use).
Compute arrival as now + remaining_duration, then display that clock in the destination zone.
Label it clearly, e.g. Arrives 2:15 PM CT (or a small TZ badge), so users aren't guessing.
Keep duration as-is; only the clock face changes. Optional: show both "2:15 PM local" and "3:15 PM your time" on long cross-TZ trips.
Re-resolve TZ if the destination is edited mid-trip.
Apple Maps and Google Maps already do destination-local arrival. Car nav systems do too. This is a display fix, not a routing change—high value, low risk.
Happy to beta-test. Thanks.
