What Is Set ClockSync II updates the following information on each Servant: • Current Date. • Current Time. • Status of Daylight Saving Time (the Daylight Saving Time flag in the "Date & Time" control panel. • City location (from the "Map" control panel). • Latitude and Longitude (from the "Map" control panel). One interesting tidbit is that many people (including Apple) pronounce DST as "Daylight Savings Time", in the plural form. It's not - we only save time once. It should be "Daylight SAVING time". For more information about the history and reasons for Daylight Saving Time, visit the web page at (http://www.energy.ca.gov/energy/daylightsaving.html).
