On this Sunday morning most of the nation will revert back to Standard time after roughly 7 months of observing Daylight Saving Time. Since Arizona, Hawaii, Puerto Rico and the eastern time zone sections of Indiana do not observe Daylight Saving Time, no time change will be needed in those parts of the country. Time changes have been mandated by the U.S. Congress. Following the old adage of "spring ahead, fall behind", you will need to turn your clocks back by one hour to conform with the local time observance.
What does this time change mean to you (other than earlier sunsets)? A change from Daylight Saving to Standard Time does not deduct an extra hour of daylight to the day nor does it affect weather patterns. While the weather will not change because of the time change, the times when you will be able to obtain weather charts will now be one hour earlier. The reason for this earlier time is that the National Weather Service always operates on "Z time" (variously called Greenwich Mean Time or Universal Coordinated Time) which does not observe Daylight Saving Time. Thus, the charts are still produced and transmitted at the same Z time.
If you change the internal clock on your computer from Daylight Saving to Standard Time, make sure that you change the setting of the time zone to reflect the change; see page 3 of the DataStreme User's Guide Manual for further instructions.
