"A clock consistently displaying the wrong time can be infuriating, but Linux offers several options to set the hour of the day."
"When Linux boots, the hardware clock is used to set Linux's own clock, called the 'system clock'. Once the system clock is set, the hardware clock is ignored until the next time you boot."
"DOS and Windows, the hardware clock is usually set to the local time, but if you only run Linux on your computer, it is possible to set the hardware clock to UTC (also known as Greenwich Mean Time or GMT) and have Linux automatically calculate the correct local time based on your time zone. This even takes into account daylight saving, so you'll have one less electronic device to change the time on twice a year. You could of course keep the hardware clock in UTC even if you were running DOS or Windows, but the time would then always be incorrect in that OS."
