Unofficial Sun Blade 100 FAQ : (Category) Sun Blade 100 hardware questions : What problems are there with the SunBlade 100 clock?
The SunBlade 100 clock runs fast by apx. 300ppm. (Sun inernal BugID 4460876, apparently affects all ‘grover’ systems) This causes it to gain 1.5 seconds per hour. This is more than xntpd can adjust, especially if you have patch 109667 (-01, -02, -03) installed. This patch prevents xntpd from ‘stepping’ the clock, only allowing gradual changes. This patch is part of the recommended set and most likely already installed on your system. Solution: add the line set sys_tick_freq = 5549020 to your /etc/system (you must reboot for this change to take effect). This will more or less correct the speed of the clock, and bring it within a range xntpd can cope with. (So this entry is probably also usefull if you don’t use xntpd) If you have the patch 109667 (-01, -02, -03) installed , you should also add this line to your /etc/inet/ntp.conf: disable pll A furture patch will allow xntpd to work with the kernel PLL again and then this line must be removed. This information is directly from Sun, but
