I am trying to change to date on my Sony dream machine alarm clock which is am/fm without cd player. It has time zone and daylight savings option. How do I change the date so that time change will happen automatically or at least take it off daylight savings time tonight so that my time will be right with the my time zone. The date on the clock is 8/10. I got this from a friend who has moved out of state and there are no instructions with the radio.
