Messages showing up with wrong date/time #9427

I'm from Mexico City. Very recently (this is the first year), Mexico has abandoned the daylight savings time program.

Seems like something in Roundcube is still forcing DST on the date it shows for messages when the time zone is Mexico City. I'm seeing messages with a time that is one hour ahead in the inbox message list. This happens with "automatic" and with "GMT -0600 America/Mexico City" timezone settings. It shows the right time if I go into a -0700 timezone like Denver, but this is obviously incorrect and will cause an issue again when they shift time again.

This is a Roundcube only issue. Messages are being displayed with correct times in other mail clients (like Outlook) for the same accounts.

The timezone database is system/PHP responsibility. So, it needs to be fixed/updated there.
