If your Phoenix TV guide is an hour early or late, check the device clock and the broadcaster's timezone before changing an app offset. Phoenix does not change clocks for daylight saving time, while another region's schedule may. The useful comparison needs the program's actual date and regional feed.
NIST explains that Arizona does not observe daylight saving time except for the Navajo Indian Reservation. A fixed year-round subtraction from an Eastern or Pacific listing can therefore be misleading.
Why did my guide become an hour out?
Choose a program on the broadcaster's current official schedule. Record its date, start time and timezone label. If there is a station or region selector, confirm it before comparing the listing with your app.
Now check the date and time on the device running the app. Set it to the actual location using its documented controls. Avoid selecting another region simply because one title then looks right; you want the clock correct for the whole setup.
Is the problem the clock or one channel's data?
Compare two unrelated channels. For each, note the official time and timezone, the app-guide time and the program actually playing. A consistent shift is a reason to inspect timezone or documented offset settings. One mismatched entry may need a guide-data or regional-feed check instead.
If the times agree but the titles differ, changing an hour offset is unlikely to help. Keep that result in your notes before refreshing or reinstalling anything.
Correct one setting, then check it
Save the original setting and a screenshot without private account details. Correct the device clock if needed, reopen the app and compare the same reference programs. Use an app-specific offset only when its documentation explains what the control changes.
Check a later program as well as the current one. If the adjustment fixes one channel but shifts the others incorrectly, restore the original value and report the affected entry.
Roku's Live TV Channel Guide documentation applies to its own interface and local settings. A different IPTV app may use a separate guide source; do not expect one platform's ZIP-code or tuner control to repair another app's listings.
Will I need to check the time again?
Revisit the comparison when clocks change elsewhere or after moving a device. Keep NIST's daylight-saving guidance with the support notes rather than relying on a remembered conversion.
For an unresolved problem, send the Phoenix viewing location, device and app, date and two concrete examples of the difference. Specify whether you were comparing a broadcast schedule, live stream or on-demand listing. That lets support investigate the same viewing route without needing your password or full playlist address.
