Fix SharePoint Online Failed to Load Current Time Zone Error
Question details
Users are encountering a time zone loading error when attempting to create or modify SharePoint list items that rely on calculated date values.

- Product
- SharePoint Online
- Device & OS
- not provided
- Scenario
- Creating or modifying SharePoint list items that use calculated date formulas, such as NOW()+70.
- Observed behavior
- SharePoint Online displays a 'Failed to Load Current Time Zone' error message and prevents the list item from saving correctly.
Ensure you have exact documentation of the calculated column formula causing the issue and check if multiple users in your tenant are experiencing the same error.
Report the Issue to Microsoft Developer Support
Because this error affects SharePoint Online backend calculations and typically impacts multiple users, it must be addressed by Microsoft's engineering team.
Time zone errors tied to calculated columns like NOW() or TODAY() are often symptoms of tenant-wide backend desynchronization in SharePoint Online.
End users cannot fix this locally. The issue must be escalated through proper administrative channels with specific tenant details to trace the server anomaly.
Note down the exact URL of the affected SharePoint list, the specific calculated-column formula being used (e.g., NOW()+70), and the exact time the error started occurring.
Navigate to the Microsoft Tech Community or Microsoft Q&A forums, which are monitored by Microsoft engineers and developer support teams.
Create a new post including your tenant details, the formula, and the scope of affected users so Microsoft can investigate the backend calculation service.

Verify Site Regional Settings
Ensure that your SharePoint site's regional settings are correctly configured, as mismatched time zones can sometimes trigger calculation conflicts.

Frequently Asked Questions
What causes the 'Failed to Load Current Time Zone' error in SharePoint?
This error is typically caused by backend server desynchronization in SharePoint Online when processing volatile functions like NOW() or TODAY() inside calculated columns.
Can I fix the SharePoint time zone calculation error myself?
Generally, no. Because it is a server-side issue that often impacts an entire tenant, it requires intervention from IT administrators or Microsoft Developer Support to resolve.
Are NOW() and TODAY() officially supported in SharePoint calculated columns?
While commonly used, volatile functions like NOW() and TODAY() are not officially supported in calculated columns because they only update when the item is explicitly modified, which can lead to calculation inconsistencies and time zone glitches.
