Roundcube: change time, date & language

If your emails show the wrong time or the interface is in a language you don’t want, you can fix both in a minute. This guide shows how to change the time, date and language in Roundcube webmail.

Open your settings

1. Log in to your webmail.
2. Click Settings, then Preferences.
3. Choose User Interface.

Change the language

In User Interface, pick your preferred Language from the drop-down. The whole Roundcube interface switches to it as soon as you save.

Change the time zone and date format

On the same screen, set your Time zone so messages show the correct local time. By default it follows the server, which is why times can look off. You can also choose how the date and time are displayed – for example a 24-hour clock or a day/month/year date.

Click Save when you are done, and your inbox updates straight away.

Why does this matter? The time zone decides the timestamp on every message you receive and send. If it is wrong, emails can look like they arrived hours earlier or later than they really did, which is confusing when you sort by date or reply to something time-sensitive. Setting it correctly once fixes this for good.

These settings are per user, so they only affect your own view. Other people using their own mailboxes are not changed, and you can adjust yours again at any time.
