I can select to have multiple timezones shown in the clocks tooltip, where I select the timezones by the names of city/region, however after the selection, the tooltip itself just presents the technical abbreviations of the timezones, e.g. PDT, CEST, AEST ... No normal user knows what these are. Please show the same names the user used to select the timezones
I found that this is now possible by checking "Display time zone as city"
Though I think this should be the default actually, it's usually the first thing I change on a new setup.
