Fixed timezone (home country time when traveling)

Hi all!
First of all, as always, thanks for a lot of good work!

I am travelling a lot for work and whenever I am in another country, the companion app as well as the browser will give all the history times in the local time of the country that I am visiting.

As lots of history data is more useful in the timezone where the HA instance is running it would be nice to have an option to set a fixed timezone to your home country, so all data is correct. I did set the timezone in the general settings but didn’t make a change.

Thanks in advance!
