You can configure your system to assume that the battery-backed CMOS
|
|
clock is set to your local legal time rather than Universal or
|
|
Greenwich time. When the system boots, the \`adjkerntz' program will
|
|
examine your current time, reverse-apply the timezone correction, and
|
|
then set the system's UTC time to the corrected value. This approach
|
|
is NOT guaranteed to always work; in particular, if you reboot your
|
|
system during the transition from or to summer time, the calculation
|
|
is sometimes impossible, and wierd things may result.
|
|
|
|
For this reason, we recommend that, unless you absolutely positively
|
|
must leave your CMOS clock on local time, you set your CMOS clock to GMT.

Unless your local time is GMT, this probably means that your CMOS
|
|
clock is on local time. In this case, the local times that you will
|
|
be shown will be incorrect. You should either set your CMOS clock to
|
|
GMT, or select option 98 from the main menu after selecting a

timezone.
