How do computers accurately track time?
487014
There are 2 clocks inside a computer.  They might be called the software and hardware clocks, with the software clock running when the computer is on.  The hardware clock uses a battery to keep running while the computer is off.\n\nThe hardware clock (also called a Real Time Clock or RTC) is a CMOS device that uses a timebase oscillator, which can only be read to the seconds accuracy.  They're not very accurate and might lose a few seconds every day.  Many times, computers will sync with the outside atomic clocks to get back on track.\n\nThe software clock is more precise, a bit prone to error, and of course, stops working when the computer is off.  It re-syncs itself with the hardware clock on boot up.

A clock/watch; a program

Tuesday\nyou can use your computer clock to find out by changing the year

You've likely changed you time-zone, so it is automatically changing each time it links up to the time-server to check.\n\nTwo options:\nFirst double click on the clock in the taskbar.\n*Now you can either disable the time-syncing feature on the "internet time tab", then rest to the correct time, or...\n*You can correct you time-zone on the "time zone" tab.\n\nEither solution should set you straight :)

If it's a Windows machine, right-click on the time display in the taskbar and select Adjust Date/Time.

Computers have TWO clocks built into them.. one being the CMOS clock,, the other being the Real Time clock..The battery keeps power going to those when the computer is not plugged into electric

Most computers have a small battery. In many cases, the battery is soldered directly onto the motherboard, but the battery is usually in some sort of holder so it is easy to replace. Computers are not the only things that have a small battery like this -- camcorders and digital cameras often have them, too. Just about any gadget that keeps track of the time will have a battery.\n\nIn your computer (as well as other gadgets), the battery powers a chip called the Real Time Clock (RTC) chip. The RTC is essentially a quartz watch that runs all the time, whether or not the computer has power. The battery powers this clock. When the computer boots up, part of the process is to query the RTC to get the correct time and date. A little quartz clock like this might run for five to seven years off of a small battery. Then it is time to replace the battery.

they get synchronized with an aytomated internet time server as \ntime.windows.com\nif there is a network problem at the moment they check their mobile phones witch are securely kept hidden in a fake sole of their shoes\nthey aslo stand some times in the center of the field where their shadows wil "inform"them about the local time.this is used in extreme moments only.

The grandfather clock works on a mechanical system of gears, spring, levers, catches and a pendulum for keeping time. Energy is stored in a wind-up spring or a weight driven axis.\n\nThe basic time keeping is achieved by a pendulum that counts time in an accurate fashion within seconds per month. This uses the principle of Periodic motion and may be adjusted to be slightly faster or slowly by shifting the pendulum ball's position slightly.\n\nThe pendulum counter then controls the movements of a system of mechanical levers, gears & wheels that are calculated to drive the second, minute and hour hands in the desired rotation ratios so that they will show the correct time.\n\nUpon the hour, the system will activate a chime via the spring driven hammers that strike tubular bells or other sounding vibrating elements. A series of activation may be composed to produce the desired melody. Some system will also provide the date for the month. In its peak, many other noviety displays such as birds, toys, animals, etc would be used to announce the top of the hour much to the delight of children and adults alike.

Yes, it is the same time here as there.  Time is an artificial construct; an illusion that we use to mark the progression of our stay on this planet.  Time doesn't truly exist, we exist and we use the various methods of measuring time (clocks, watches, egg timers, etc.) to keep track of how long we are in existence.

yes that is true\n\nClick on your clock on your pc then click time zones, it will show you all of them
