Hi! I see you're having an issue where the DreamMapper (Reaper) app is saying your iPhone time is incorrect in Arizona. Let's get this sorted out together.

First, just to clarify a couple of things:
- Is your iPhone’s date, time, and time zone set to update automatically?
- What does the app show as the incorrect time? Is it off by a few hours or something else?
- Also, are you using any VPN or location services that might affect time settings?

Meanwhile, here’s a step-by-step you can follow to start troubleshooting:

1. Check iPhone Date & Time Settings:
- Go to Settings > General > Date & Time.
- Make sure Set Automatically is turned ON. This lets your iPhone sync the time based on your location, which should work fine for Arizona.
- Also, verify that your Time Zone is set to Arizona or automatically detected.

2. Restart the DreamMapper App:
- Close the DreamMapper app completely by swiping it away in the app switcher.
- Reopen the app to see if the time syncs correctly.

3. Update the DreamMapper App:
- Open the App Store, go to your profile, and check if there's an update available for DreamMapper.
- If yes, update the app to ensure it works with your iOS version 18.7.

4. Restart Your iPhone:
- Sometimes, a simple reboot can resolve time sync issues.

5. Check for any App-specific Time Settings:
- Open DreamMapper and look for any settings menu related to device or time.
- If available, try toggling or resetting the time zone in the app.

If you've tried all of these, and the time is still off, sometimes the DreamStation device itself may have an incorrect time setting that can affect the app.

6. Check the DreamStation Device Settings:
- On your DreamStation device, hold down the dial and ramp button together for five seconds to access the device menu.
- Navigate to the time or clock settings and verify they're correct for Arizona (Mountain Standard Time, no daylight savings).
- Adjust if needed.

If after this, the app still shows the wrong time, please let me know. We can look into more advanced troubleshooting or check for any account sync issues.

Are you comfortable trying these steps? Also, did you notice if this started happening after any recent updates or changes?
