Getting "absolute" time in Linux



Is there a way in either standard or Real-time Linux to get "absolute number of ticks (or seconds) since the Epoc (or some other configurable starting point), regardless of the kernel clock resets via settimeofday() and the RTC resets via hwclock set and regardless of the system reboots?
