Setting the Time Zone

Setting the Time Zone

You are next shown a Time Zone Selection dialog (see Figure 1.19). There are two "clocks," or times, when using a PC: the hardware clock, maintained by hardware in the computer and a backup battery; and the system time, set upon booting and used by the Linux kernel. It is important to keep the two times accurate and in synchronization because automated system administration might need to take place at critical times. Many computer installations use computers with hardware clocks set to GMT, which stands for Greenwich mean time. The more modern designation is UTC or coordinated universal time. The Linux system time is set relative to this time and the default time zone, such as eastern standard time, which is -5 hours of UTC.

Setting the computer's hardware clock to UTC (GMT) has the advantage of allowing the Linux system time to be easily set relative to the geographic position of the computer and resident time zone (such as a Linux laptop user who would like to create files or send electronic mail with correct time stamps, and who has traveled from New York to Tokyo).

Choose your time configuration, and then click Next.
