So. if you didn't set your clocks back would you arrive to work early or late? That still boggles my mind.
Before I was married, I just remembered that the actual time was an hour earlier or an hour later than the clocks read or, more practically, I'd consult my watch.
Every time piece except my watch changes automatically, so I simply set it back or forward before I go to bed. Problem solved. Learned the hard way.
A little bit scary, though, Von. When they change the day that daylight times begins and ends, the computer knows that it has changed. How ?
Good heavens. When we were working we simply adjusted the clocks when we went to bed. Now that we're retired, we just change them when we get up in the morning. (Though I'm usually still awake at 2 a.m. anyhow. )
I dislike DST also. Messes with my very being. Normally I change clocks before going to bed. Last year and probably this year will change once I get up tomorrow.
Your computer has a built-in clock and when you initially set the computer up, you indicate your time zone. It calculates the DST changes. Here's an explanation: Computers have a "real-time clock" -- a special hardware device (e.g., containing a quartz crystal) on the motherboard that maintains the time. It is always powered, even when you shut your computer off. Also, the motherboard has a small battery that is used to power the clock device even when you disconnect your computer from power. The battery doesn't last forever, but it will last at least a few weeks. This helps the computer keep track of the time even when your computer is shut off. The real-time clock doesn't need much power, so it's not wasting energy. If you take out the clock battery in addition to removing the main battery and disconnecting the power cable then the computer will lose track of time and will ask you to enter the time and date when you restart the computer. Also, on many computers, when you connect your computer to an Internet connection, the OS will go find a time server on the network and query the time server for the current time. The OS can use this to very accurately set your computer's local clock. This uses the Network Time Protocol, also called NTP.
