If your espruino is connected to another device that knows the time,timezone and daylight saving, it could be easy (over Wifi or Xbee in my situation). In my setup i transfer seconds after EPOC (1970) minus/plus the differece to UTC to the espruino. I set the time with setTime on the espruino side then ignore the timezome at all. The time it self is correct ignoring the timezone (UTC) on the espruino at all.
