Choosing Pacific Standard/Daylight Time vs. GMT on Calendar and iCloud

Hi alice dale,

If you haven't done so yet, restart your iPhone. Although simple, this step can help correct some unexpected issues. It's also a good idea to make sure your iPhone is running the latest iOS version, since this can help with overall performance: Update your iPhone or iPad

If an update is available, be sure to create a backup before installing it.

1. Back up your device using iCloud or your computer.

2. Plug your device into power and connect to the internet with Wi-Fi.

3. Go to Settings > General, then tap Software Update.

4. If you see more than one software update option available, choose the one that you want to install.

5. Tap Install Now. If you see Download and Install instead, tap it to download the update, enter your passcode, then tap Install Now. If you don't know your passcode, learn what to do.

If the issue continues, make sure the setting is correct in Settings > General > Date & Time. If you're having trouble changing it there, these steps will help: If you can't change the time or time zone on your Apple device

Here's some additional information that may be helpful: Add calendar events in other time zones on iCloud.com

If more help is needed, reach out to Apple Support directly so they can look into this with you further. They can be contacted here: Get Support or by calling the most applicable phone number from this list: Contact Apple for support and service.

Regards.
