No. You have to tweak the kernel. If you have the PPSkit:
| $ echo 0 > /proc/sys/kernel/time/rtc_update
Otherwise you have to patch time.c in the kernel. Dead easy, just a
matter of commenting out a line or two. I'm so patching all my kernels,
reading and writing the RTC exclusively with hwclock 2.31, and am
getting a far better accuracy.
The main purpose of an RTC is to initialise the system time at powerup,
isn't it? Most people startup in the morning at around half a second of
the true time, and later ntpd has to step this to UTC. I routinely
startup at some low milliseconds of the true time, offset quickly
slewed. My last step event was years ago.
