+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.
