Hi there, @Raemondo. Welcome to the Fitbit Community Forums. Thanks for bringing this to my attention. I'm sorry to hear that your Inspire is not showing the correct time zone. I understand your concern, I will do my best to help you with this!
Is your Inspire syncing properly? Please note that the time will be wrong if your Inspire hasn't set up just yet or synced recently as your Fitbit device uses the time of the device you're syncing with. To make sure your Fitbit device has recently synced, go to your Fitbit app and tap the Today tab, and then tap Devices.
If by any chance you run into syncing issues, please see Why won't my Fitbit device sync?
If the issue is still not solved, but you can confirm that your Fitbit device is syncing, I recommend changing your time zone one more time to a completely different one, sync your device, put the correct time and sync again.
Regarding your inquiry about the battery, please note we as Fitbit do not do it or suggest to replace the battery as that could permanently damage your watch. The battery on Fitbit devices are not replaceable nor interchanged.
Before doing something to your Fitbit device, please review the section Availability or repair facilities/spare parts and Exclusions and Limitations from this article fitbit.com/legal/returns-and-warranty.
