Distance Calculator

This form uses data from the US Census and a supplementary list of cities around the world to find the latitude and longitude of two places, and then calculates the distance between them (as the crow flies). It can also provide a map showing the two places, using the Xerox PARC Map Server.

Bibliography on Computer Network Time Synchronization

Weather observations are always taken with respect to time. Thus all observations have a corresponding time, and that time is reported along with the measurement. By convention, weather scientists use the twenty four hour clock, and use one time zone, Greenwich Mean Time (GMT). This time is also known as Universal Time (UTC). To convert to local time, we must know the time difference between GMT and local time for both standard time and summertime (daylight savings time). Not all states use daylight savings time in the summer.
