Question

How do I change the clock in Outlook to Daylight Savings Time?

Answer 1

Hi @Chris Moore, 

Welcome to Microsoft Q&A forum.  

Thank you for reaching out regarding the clock in Classic Outlook and Daylight Saving Time. According your concern, classic Outlook does not have its own setting to enable or disable Daylight Saving Time. Instead, it uses the date, time, and time zone configuration from your Windows system. This means that any daylight saving adjustment must be managed directly in Windows rather than in Outlook itself. 

To ensure the correct time is displayed, please check your Windows time settings by going to Settings > Time & Language > Date & Time. From there, confirm that the correct Time zone is selected, and make sure you choose a time zone that supports Daylight Saving Time. Also verify that the option “Adjust for daylight saving time automatically” is enabled. Once these settings are active, Windows will automatically apply the daylight saving adjustment, and Outlook will reflect the updated time accordingly. 

 

After enabling the setting, you will need to close and reopen Outlook to ensure it refreshes with the updated system time. 

I hope this information is helpful. Please follow the steps above and let me know if it works for you. If not, we can continue working together to resolve the issue.  

Thank you for your patience and understanding. If you have any questions or need additional assistance, please don’t hesitate to reach out so I can continue to support you. If you found the response useful, please consider marking it as accepted, as this may help other community members who are looking for similar guidance.  

I look forward to continuing the conversation.

Outlook does not have its own separate clock. It always uses the Windows time zone and Daylight Saving Time (DST) settings. To have Outlook show the correct Daylight Saving Time, configure DST in Windows:

1. Open Start > Settings > Time & language > Date & time.
2. If Set time zone automatically is On, Windows (and therefore Outlook) will adjust for DST automatically.
3. If Set time zone automatically is Off:
   • To adjust for DST automatically, turn Adjust for daylight saving time automatically On.
   • To manage DST manually, turn Adjust for daylight saving time automatically Off and then set the time manually as needed.

Outlook will use these Windows settings to calculate and display meeting and appointment times correctly, including the DST offset.
