hwclock 执行出现的报错信息

IBM 3850升级微码后，发现一个问题，系统时间变快了8小时。date -s 更改后，clock -w和hwclock都报以下错，select() to /dev/rtc to wait for clock tick timed out。重启机器后还是时间仍然没有更改过来。在 /etc/sysconfig/clock里加了一条 CLOCKFLAGS=--directisa 再hwclock --directisa。修改时间：date MMDDhhmm保存修改：hwclock -w --directisa在设置系统时间的时候遇到以下问题 :hwclock --showselect() to /dev/rtc to wait for clock tick timed out解决办法:vi /etc/sysconfig/clockHWCLOCKPARS=--directisa或者在命令行:hwclock --show --directisa (在hwclock命令中加上参数--directisa即可)Functions:--help        show this help--show        read hardware clock and print result--set         set the rtc to the time given with --date--hctosys     set the system time from the hardware clock--systohc     set the hardware clock to the current system time--adjust      adjust the rtc to account for systematic drift since                the clock was last set or adjusted--getepoch    print out the kernel's hardware clock epoch value--setepoch    set the kernel's hardware clock epoch value to the                value given with --epoch--version     print out the version of hwclock to stdoutOptions:--utc         the hardware clock is kept in coordinated universal time--localtime   the hardware clock is kept in local time--rtc=path    special /dev/... file to use instead of default--directisa   access the ISA bus directly instead of /dev/rtc--badyear     ignore rtc's year because the bios is broken--date        specifies the time to which to set the hardware clock--epoch=year specifies the year which is the beginning of the                hardware clock's epoch value--noadjfile   do not access /etc/adjtime.
