An hour offset in Dynamics is typically caused by a time zone or daylight saving mismatch between Windows, the Dynamics user settings, and how the app renders the date/time value.
- Verify the Dynamics personal time settings:
- In Dynamics 365, select Settings in the upper-right corner.
- Select Personalization Settings.
- On the Formats tab, confirm the Date Format and Time Format match the regional format in use.
- Check the Time Zone setting in personal options and make sure it matches the local region.
- Verify Windows time zone and DST settings:
- Go to Start > Settings > Time & language > Date & time.
- Confirm the correct Time zone is selected.
- If the time zone is set manually, make sure Adjust for daylight saving time automatically is enabled when applicable.
- Check for a browser locale mismatch:
- If the browser language/locale differs from the Dynamics format settings, the schedule board and other date/time displays can show incorrect times.
- Make the browser locale match the Dynamics regional format, then refresh the page.
- Determine whether the problem is in the stored value or only in the display:
- Open the activity record directly in Dynamics and check the date/time field there.
- If the record shows the correct time but another view shows it one hour off, that points to a client-side rendering or DST issue.
- If the stored value itself is wrong, review whether the column uses User Local, Time-Zone Independent, or Date only behavior, because those display differently.
- If the issue happens around a daylight saving transition:
- Dynamics can show shifted times across a DST boundary in some views.
- If records are correct but the board or app view is off by one hour, test a date after the DST transition to confirm whether the rendering path is applying the wrong UTC offset.
If Windows shows the correct local time and only Dynamics activities are off by one hour, the most likely fix is correcting the Dynamics user time zone/format settings and ensuring they align with Windows and the browser locale.
