Date, clock and time zone settings
Hello,
What is difference between " 1. Hardware set to local time 2. Hardware clock set to UTC And what does the following mean. 3. NTP server - automatic time synchronization (using NPT ) Thanks Varun |

If you set your BIOS clock to local time (normal time when you look at your watch) then it's (1). If you set your BIOS clock to UTC (which is kindof like GMT but does not change with daylight savings time) then you will have to create offsets to your local time. If you live in England you use UTC+0 (or +1 for DST) if you live in Kiev you use UTC+2, etc. If you boot a few OS on one box you should use UTC or you will get confused with all the settings. Quote:

Obviously you can find lots of information on the subject by just googling. You will find that time can be very complex.
In a nutshell the clock in your computer is not very accurate over a long period of time and will drift. A NTP server is a computer that is connected to a very accurate time standard clock. The ntp deamon automatically sets your system clock to the time standard, compensates for network delays and clock drift. The main difference between running ntp and just manually changing your clock time is that you can not compensate for drift. The only time it really matters if your clock it set to UTC versus local time is if you are dual booting. Windows expects the clock to be set to local time. |
All times are GMT -5. The time now is 07:27 AM. |
