How to set time and time zone?

Hi, is there a guide of how to setup the clock?

I’m trying to use the alarm function on both Volumio and LMS, but it doesn’t work. So I guess the time is wrong. But I see no option for changing it or even how to know what time the system is using.

Never mind, already did it via ssh in Mac terminal.

For anyone that wants to know how… Link below.
