What
Time is It, Satellite Time? The satellite gives times to scientists according to Greenwich Mean Time (GMT). GMT is an international time-keeping standard. It is based on the local time in Greenwich, England. Greenwich Mean Time is also called Universal Time (UT). When measuring time with GMT or UT, it's the same time everywhere on earth! That's why it's considered "universal time."
GMT was invented to avoid the confusion that using "local" or "solar time" causes when referring to events that are taking place in different time zones.
So what time IS it where the eagles are, local time? After all, local time DOES matter to an eagle whose behavior is regulated by earth's day/night cycles. Because the eagles are in the Eastern Time Zone, they are 5 time zones to the west of Greenwich, England. This means that local time for our eagles is 5 hours EARLIER than Greenwich Mean Time.
