A trip through time - Measuring time

Humanity’s longstanding quest to record and measure time has moved past keeping track of months and years and into the realm of keeping track of nanoseconds and beyond. Our ability to determine who wins an Olympic event by a fraction of a millisecond often seems to overshadow the fact that we are still recording millennia events, like global warming, as well. The advent of time zones has enabled us to formally acknowledge that it is not the same time everywhere in the world all at once. Because of the way the earth rotates on its axis, when it is morning in the western hemisphere, it is evening in the east; today is someone’s yesterday at the same time it is someone else’s tomorrow. Various time standards have been established to homogenize how time is handled on a global scale. Time has been organized in different ways, some based upon the actual movement and location of the earth, while others are based upon man’s interpretation of it. No matter which system of measurement we adhere to, adjustments will need to be made occasionally to keep it all in sync. Currently a mixture of leap years, the less known leap seconds, and in some places, daylight savings time, helps compensate for the natural wavering of the system we record. These units, time zones, time standards, and even the necessary exceptions to time measurement all play a unique role in forging the perception of time we have today.
