My openmoko does a suspend/resume cycle every 10 minutes. RTC time can only be set at one second granularity. If I write to RTC on every suspend cycle inaccuracy starts to accumulate. My solution: Never write to RTC. I let the RTC drift as freely as it wants and always just set the system time based on RTC. I have calculated how much the RTC drifts so it is not a problem that the RTC is actually already an hour off-the-UTC :-) Some benchmarks: http://lists.openmoko.org/pipermail/openmoko-kernel/2009-May/010161.html Patch to make hwclock easier to use when RTC is wildly off-the-UTC (upstreamed a year ago): http://www.spinics.net/lists/util-linux-ng/msg03026.html -- To UNSUBSCRIBE, email to debian-devel-requ...@lists.debian.org with a subject of "unsubscribe".
