Chapter 13 Maintenance Table 33 Maintenance > Time LABEL Time Zone Setup Time Zone Daylight Savings DESCRIPTION Choose the time zone of your location. This will set the time difference between your time zone and Greenwich Mean Time (GMT). Daylight saving is a period from late spring to fall when many countries set their clocks ahead of normal local time by one hour to give more daytime light in the evening. Start Date Select this option if you use Daylight Saving Time. Configure the day and time when Daylight Saving Time starts if you selected Daylight Savings. The o'clock field uses the 24 hour format. Here are a couple of examples: Daylight Saving Time starts in most parts of the United States on the second Sunday of March. Each time zone in the United States starts using Daylight Saving Time at 2 A.M. local time. So in the United States you would select Second, Sunday, March and type 2 in the o'clock field. End Date Daylight Saving Time starts in the European Union on the last Sunday of March. All of the time zones in the European Union start using Daylight Saving Time at the same moment (1 A.M. GMT or UTC). So in the European Union you would select Last, Sunday, March. The time you type in the o'clock field depends on your time zone. In Germany for instance, you would type 2 because Germany's time zone is one hour ahead of GMT or UTC (GMT+1). Configure the day and time when Daylight Saving Time ends if you selected Daylight Savings. The o'clock field uses the 24 hour format. Here are a couple of examples: Daylight Saving Time ends in the United States on the first Sunday of November. Each time zone in the United States stops using Daylight Saving Time at 2 A.M. local time. So in the United States you would select First, Sunday, November and type 2 in the o'clock field. Apply Cancel Daylight Saving Time ends in the European Union on the last Sunday of October. All of the time zones in the European Union stop using Daylight Saving Time at the same moment (1 A.M.
