Thanks - that confirms my LA theory

root@openHAB:~# openhab-cli console -p habopen env | grep timezone
String user.timezone America/Los_Angeles
root@openHAB:~# ls -l /etc/localtime
lrwxrwxrwx 1 root root 35 May 4 14:45 /etc/localtime -> /usr/share/zoneinfo/Australia/Perth
root@openHAB:~# cat /etc/timezone
Australia/Perth
So my system TZ = Australia/Perth, but Java TZ is America/Los_Angeles
I have read the link you pointed me to … but it does not mention a fix.
How do I get the Java TZ correct?
