How can Changing Time Zone

I changed time zone in my profile but it did not change in my channel

How can I change it ?

The field plots will use your system time zone set for your computer. Custom code will use your set timezone. For example, if you write a MATALB analysis that says

datetime('now')

It will show the time in the time zone set by your ThingSpeak profile.

Can you describe more specifically what exactly you want to see? Then we can help you add code to a custom visualization that will display as you wish.
