Calendar; displaying second time zone

[Overlander]

Those who live and work in a different time zone than those they are working with, or they live in a different time zone than their family and friends live in, might find it helpful to have a second time zone shown in the calendar tab. I come from Outlook, and I had it there. It helped a lot to when negotiating which time an event/meeting/call should be scheduled for.

Recent post-Outlook user and agree, this is valuable for any users managing calls/invites with people across timezones, which is a lot of users. 

Below is a mockup from another user requesting it on Thunderbird reddit thread, and my screen shot on where the setting should be added for enabling/disabling the feature. 

Under Settings > Calendar > Near the 'set manual timezone' option, Add new options for 'Show multiple timezones' and allow radio dropdowns for non-default timezones. 

When enabled, show other times with the zone label/name in the calendar view.
