| 6 | <para>The setclock script is only for real use when the hardware clock (also
|
|---|
| 7 | known as BIOS or CMOS clock) isn't set to GMT time. The recommended
|
|---|
| 8 | setup is setting the hardware clock to GMT and having the time converted
|
|---|
| 9 | to localtime using the /etc/localtime symbolic link. But if an
|
|---|
| 10 | OS is run that doesn't understand a clock set to GMT (most notable are
|
|---|
| 11 | Microsoft OS'es) you may want to set the clock to localtime so that
|
|---|
| 12 | the time is properly displayed on those OS'es. This script will then
|
|---|
| 13 | set the kernel time to the hardware clock without converting the time using
|
|---|
| 14 | the /etc/localtime symlink.</para>
