Overview
Roundcube lets you set your preferred timezone so that message timestamps and calendar events display in your local time. This guide applies to Roundcube 1.4+ and later versions.
Steps to Change the Timezone
- Log in to your Roundcube webmail account.
- Click the Settings icon (gear) in the top-right corner of the screen.
- In the left-hand panel, expand Preferences and select User Interface.
- Locate the Timezone dropdown menu.
- Select your desired timezone from the list. Timezones are listed by region (e.g.,
Africa/Johannesburg,America/New_York,Europe/London). - Click the Save button to apply your changes.
Important Notes
- Roundcube uses IANA timezone identifiers (also known as "Olson" or "tz database" names).
- Changing the timezone only affects how times are displayed in your Roundcube interface — it does not alter the original timestamp of your emails.
- Daylight Saving Time (DST) adjustments are handled automatically when you select a region-based timezone.
- If you leave the timezone set to
Automatic, Roundcube will attempt to detect your timezone from your browser settings.
Troubleshooting
- My timezone is not listed: Choose the nearest major city in your timezone region. IANA timezone names are city-based and cover all standard time offsets.
- Timestamps still appear incorrect: Ensure your browser is not overriding the setting. Try setting a specific timezone instead of
Automatic, then log out and log back in. - Setting does not appear: Your hosting provider may have restricted this preference in Roundcube. Contact support for assistance.
