Q: ICloud Calendar on my computer

Hello jwmeinecke,

I'm sorry to hear you are having these issues with your devices and iCloud. If your events are consistently being offset by three hours but your time zone settings are the same, you may want to make sure that Time Zone Support/Time Zone Override are not enabled on either your iOS devices or iCloud. You may find the information and steps outlined in the following articles helpful:

Sincerely,
