How to adjust time (Daylight Savings Time) in Volumio?

I use Volumio as my alarm clock. after Daylight Saving Time goes into effect, I have to adjust all alarms by 1 hour, and then back again in the fall. How do I adjust the system time of the Raspberry Pi?

Maybe if you ssh into it the standard Linux dare command will work?
