Thanks for your > help .. Yes, it's because you've reset the clock. If you're not using other OS that don't support this, you should consider to use the UTC for the hardware clock. The glibc then cares for the daylight savings time and timezone. When you reset the clock, hwclock does interpret this as correcting a wrong time and calculates the drift from that and write it to /etc/ adjtime. You should replace the first number in /etc/adjtime to "0.0" to reset the drift. Otherwise your hardware time will be reset on next boot with the calculated drift. It's off again, then. That's because time is read only at boot time and may be written to the hwclock at shutdown (depends on boot scripts, but i think it's done this way). On next bootup the hw clock is supposed to be off depending on the drift and is "corrected" then. So it seems to me that your problem is not yet solved... But it's easy to do as you see. HWH PS: You seem to live in a german speaking area like me, so this may be interesting: http://www.linux-ag.de/linux/LHB/node149.html it's a little out of date (uses "clock" instead of "hwclock") but the general concepts are well described. -- gentoo-user@gentoo.org mailing list
