Hi,  
I'm trying to set the timezone in my node-red to Australia/Perth.

The node-red is running on Ubuntu 22.04, the system timezone was set to Australia/Perth. This is the output of `date` command.

However, in node-red, the timezone is Australia/Sydney.

I also tried to add `process.env.TZ=Australia/Perth` but still no luck. I restart my node-red everytime I change the settings.js and system time.

The wrong timezone makes the x-axis of my line chart incorrect, the x-aixs is also showing Sydney time instead Perth. Any help would be appreciated!

Thanks!

How are you running node-red (docker container?)

What do you see if you use an exec node to run the `date` command?

If you press `ctrl-shift-p` and enter "system info", what does it reveal?

> How are you running node-red (docker container?)

- I'm not using docker, I'm using systemd on ubuntu 22.04, I have my own systemd file (node-red-ps.service).

> What do you see if you use an exec node to run the `date` command?

- The exec command gives the correct output

> If you press `ctrl-shift-p` and enter "system info", what does it reveal?

- Everything looks correct in system info

[UPDATE]

- Reboot server does not help
- Changing timestamp node to Json Date object prints the correct time (and timezone), seems like only node-red itself uses incorrect timezone

Where is the value shown coming from?

Can you try a different browser?

Hi,

> Where is the value shown coming from?

This came from an timestamp inject node.

> Can you try a different browser?

I just realize that setting up `process.env.TZ works`, the timezone printed in the node-red console and the axis of charts use the browser timezone.

Thank you all for helping
