If you recently updated your RoundCube Webmail and noticed that the email received date is missing both on mailbox pane and the email itself, this is because your “date.timezone” PHP setting is either commented or use the wrong setting.
To resolve this matter, edit your “php.ini” file :
/etc/php.ini
And find the following parameter (it should be around line 946) :
;date.timezone =
And change it to :
date.timezone = "UTC"
You may now restart your Web server service to make this change effective.
