Bug in docu chirpstack-application-server.toml

[metrics]
timezone=“Europe/Amsterdam”

The whole timezone parameter seems not supported. Generates error message:

time=“2021-03-29T06:39:18Z” level=fatal msg=“setup storage error: set time location error: load location error: unknown time zone Europe/Amsterdam”

Explanation of time zone loading in Go is here:

https://golang.org/pkg/time/#LoadLocation

Also make sure you have the time zone files available.
