Fix OneDrive iOS Camera Upload Using Wrong Time in Filenames
Question details
The user's OneDrive app generates filenames with UTC or GMT timestamps instead of the local time when uploading photos from an iOS device camera roll.

- Product
- Microsoft OneDrive
- Device & OS
- iOS
- Scenario
- Automatically backing up photos from an iPhone or iPad to Microsoft OneDrive using the Camera Upload feature.
- Observed behavior
- Even though the original photo metadata and iOS device time are correct, the generated filenames in OneDrive use an incorrect UTC/GMT time.
Ensure you have your Microsoft 365 account credentials handy, as you will need to log in to the web version of OneDrive to adjust administrative settings.
Update Microsoft 365 Language and Time Zone Settings
Correcting the time zone in your Microsoft 365 web settings ensures that the OneDrive server processes uploads using your local time instead of defaulting to GMT.
OneDrive often defaults to server time (UTC/GMT) if the account's regional settings are unconfigured or incorrectly synced. Updating this via the web portal forces the mobile app to respect your local time zone.
Open a web browser, navigate to the OneDrive website, and sign in with your Microsoft 365 account.
Click on the gear icon (Settings) located in the top-right corner of the interface.
Look for the Microsoft 365 section and click on 'View all' to open the extended account preferences.
Select 'Language and time zone', choose your correct local time zone from the dropdown menu, and save the changes.

Verify iPhone Date and Time Settings
Ensuring your iOS device is set to detect time automatically prevents conflicting time data from being sent to OneDrive.
Reinstall the OneDrive iOS App
A fresh installation clears cached configurations and forces the app to pull the most recent account settings from the Microsoft servers.

Frequently Asked Questions
Why does OneDrive change the timestamp to GMT during backup?
OneDrive defaults to the server time (UTC/GMT) when it processes uploads if your Microsoft 365 account time zone is not explicitly configured or fails to sync properly with the app.
Does the wrong filename time change the actual photo metadata?
No. The underlying EXIF data (metadata) embedded in the original iOS photo usually retains the correct local time and location data. Only the filename generated by OneDrive is affected by this specific issue.
Will reinstalling the OneDrive app delete my files?
No. Deleting the OneDrive app from your iPhone only removes the app itself and local cache. Your uploaded photos and documents are safely stored in the cloud and will reappear once you reinstall and log back in.
