Daylight Saving Time ?

[bgroper]

IIRC GPS gives universal time, in UTC.
For the correct timezone, its up to the device to know (eg a watch or phone) or be told (eg computer) what timezone the user is in.
So I guess the car would need an additional tz setting saved in userspace, or do it automatically like a watch using GPS position.
Seems an easy opportunity for improvement. Should be low hanging fruit for VAG.
