Time zone setting

Hi, just a simple question. I am setting the Time zone in configuration.yaml as:

Pick yours from here: http://en.wikipedia.org/wiki/List_of_tz_database_time_zones

time_zone: UTC+01:00

However this gives a Config Check error. It is according the wikipedia list.
What is wrong here?

Try using the TZ database name. In your case this might be: Europe/Paris

Where do you see this in the Wikipedia list? It isn’t there. There is /Etc/GMT+1 - but that is not what you wrote.

You are better to use a timezone attached to a place name as suggested by @sj3fk3 - you will then get adjustments for summer time etc.

The preset in a new configuration.yaml is “UTC”
I ended up on a wrong wiki page https://en.wikipedia.org/wiki/List_of_time_zones_by_country
But solved now!
Thanks
