As I wrote before, it's look like impossible to use RTC, because it already used for statistics gathering and for profiling. So on a FreeBSD time resolution is limited by clock frequency, usually it's equal 100 Hz, in the Linux case it's limited by max RTC frequence that equal (?) 1024 Hz. -- Vladimir Silyaev To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-emulation" in the body of the message
