hwclock命令参数及用法详解,转载自:http://www.linuxso.com/command/hwclock.htmlhwclock(hardwareclock)功能说明:显示与设定硬件时钟。语法:hwclock[--adjust][--debug][--directisa][--hctosys][--show][--systohc][--test][--utc][--version][--set--date=
Suppose you start with no adjtime file. You issue ahwclock--set command to set the Hardware Clock to the true current time.Hwclockcreatesthe adjtime file and records in it the current time as the last time the clock was calibrated. 5 days later, the clock has gained 10 seconds, so you ...
-w --systohc,将硬件时间调整为和系统时间一致以系统为准 Linux时钟 系统时钟 是指当前Linux Kernel中的时钟 硬件时钟 是主板上由电池供电的时钟,可以在BIOS中进行设置 1.当Linux启动时,硬件时钟会去读取系统时钟的设置,然后系统时钟就会独立于硬件运作 2.Linux中的所有命令(包括函数)都是采用的系统时钟设...
所有Linux相关指令与函数都是读取系统时钟的设定。 语法 hwclock(选项) 选项 --adjust:hwclock每次更改硬件时钟时,都会记录在/etc/adjtime文件中。使用--adjust参数,可使hwclock根据先前的记录来估算硬件时钟的偏差,并用来校正目前的硬件时钟; --debug:显示hwclock执行时详细的信息; --directisa:hwclock预设从/...
This ensures that it always terminates, but not correctly nor in the manner intended (nor was the intent of that change to fix the bug described above). We want to change the hwclock to the one as viewed on the date command.Environment Red Hat Enterprise Linux 6.4 util-linux-ng 2.17.2...

I'm trying to set up a DS3231 hardware clock and the system can't find the hwclock command. I installed the util-linux command as other references suggested, but the command still isn't there. Thank you
