From: Christian Hitz <christian.hitz@bbv.ch>

When we configure a time zone on our device's GUI we use the standard
time zones. This gives us the usual benefits e.g. automatic daylight
saving time switching.
We also need to support an API that wants to set the "time zone" by
specifying the offset in minutes from GMT. The given information
is not enough to reliably selecting one of the existing time zones.
Instead, when the time zone is set over this API we dynamically create
and configure a "Custom" time zone with the given offset. For this
we use the `zic` tool on target.
