Time

As we prepare for the annual late winter shift from standard time to Daylight Savings Time, it would hardly be remiss to mention the Official US Time website, a public service provided cooperatively by the two federal agencies of the United States concerned with time measurement: the National Institute of Standards and Technology (NIST) of the Department of Commerce, and its military counterpart, the US Naval Observatory (USNO). As they observe, “readings from the clocks of these agencies contribute to world time, called Coordinated Universal Time (UTC). The time maintained by both agencies should never differ by more than 0.0000001 seconds from UTC.”

The site offers a number of features and links which may well be of interest, allowing you to set your computer clock with the internet using either the National Institute of Standards and Technology or the US Naval Observatory; a Map of US Time Zones specifying those areas which do not observe Daylight Savings Time; a Map of World Time Zones; and a calculator for Astronomical Time and Date information for sunrise, sunset, moonrise and moonset either for cities and towns in the US or for specific geographical locations worldwide.

You’ll find a number of other websites relating to clocks and time in the appropriate section of our Hitchhiker’s Guide to the Web, and other related links in the HHG section on Calendars.
