94 CHAPTER 5: MANAGING SYSTEM INFORMATION ■ Daylight Saving - Enables setting automatic Daylight Savings Time (DST) on the device, either on a non-recurring or recurring basis. In the non-recurring case, DST is configured to apply to one specific period of time only, defined by specifying the begin and end times, months, days, and years. Non-recurring settings need to be changed every year. In the recurring case, the year is not specified, so that the time and date settings apply to every year. The possible field values are: ■ USA - The device switches to DST at 2:00 a.m. from the second Sunday in March, and reverts to standard time at 2:00 a.m. on the first Sunday of November. ■ European - The device switches to DST at 1:00 am on the last Sunday in March and reverts to standard time at 1:00 am on the last Sunday in October. The European option applies to EU members, and other European countries using the EU standard. ■ Other - The DST definitions are user-defined based on the device locality. If Other is selected, the From and To fields must be defined. ■ Time Set Offset - Sets the offset (in minutes) to be applied to the system time at the beginning and end of DST. The default is 60 minutes. The field range is 1-1440. ■ From - Configures the non-recurring time and date on which DST begins in countries other than the USA and Europe. The fields to set are: ■ Hours - The hour of the day at which DST begins. The field range is 0-23. ■ Minutes - The minute of the hour at which DST begins. The field range is 0-59. ■ Month - The month of the year in which DST begins. The field range is 1-12. ■ Day - The day of the month at which DST begins. The field range is 1-31. ■ Year - The year in which DST begins.
