After a reboot I am sure the boot time hwclock set the time. The system time set by date evaporates when the system shuts down. System time is not preserved across reboots. But at boot time the boot time script /etc/init.d/hwclock.sh sets the time from the hardware clock. Best is to install ntp and have it set the time from the network at boot time. apt-get install ntp If you don't have a network then of course ntp can't work. For systems such as the Raspberry Pi that don't have a hardware clock the time is set to a best guess based upon the most recent timestamp on a statefile in the file system to keep time moving forward.
