Timezone changes to default

Hi,

I have an issue with the time settings.

Changed time and date with date -s and reconfigured the timezone using dpkg-reconfigure tzdata.
Then I stored the settings to the hw-clock: hwclock -w

This works fine and after a soft restart the right time is available.
But after one day - probably after the machine was shut wodn over night - the timezone changes back to default.

Did I miss an option to store the timezone?
NTP-Server is not used, as the device will used in the local network only.

Thanks in advance

Hi,

I found the troublemaker...

I have the IoT dashboard from another thread implemented and there was a node that sets the timezone to north america. It can be that easy, if you know where your troubles come from
