Bug#1080311: railway-gtk: should handle timezones in a better way

[Martin]

Package: railway-gtk
Version: 2.4.0-4

Dear maintainer,

if users system has a different timezone then the train operator (common
use case when planning a trip in a different country), it's not obvious,
which time is used where.

E.g. if users system runs in UTC, searching for a connection in Germany
(CEST/UTC+2 atm.) at 16 hrs, this is interpreted as 16:00 UTC and it
shows a train at 18:00 CEST.

This is technically correct, but confusing. Web sites of train operators
interprete search time always as local time of the train, no matter
which is the time zone of the users system, which is better UX IMHO.

Alternatively, times zones could be displayed with the times, but that
would clutter the UI. Not so nice on mobile phone.

The obvious workaround would be to run railway-gtk with the desired
timezone, but it looks like railway-gtk ignores the TZ variable!

Cheers
