What is the most someone can lose the popular vote by but still win the electoral college? As of v2.26 it will no longer automatically use directisa when the rtc driver is unavailable; this was causing an unsafe condition that could allow two processes to access the Hardware One area that seems to have no documentation is the 'right' directory of the Time Zone Database, sometimes called tz or zoneinfo. hwclock sets the kernel's timezone to the value indicated by TZ or /etc/localtime with the --hctosys or --systz functions. have a peek here
To revert to the default, issue the command echo 0 > /proc/sys/xen/independent_wallclock Before update: It is probably a virtualization issue. An example is the vfat filesystem. Either --utc or --localtime must be specified when using this option. --adjfile=filename Overrides the default /etc/adjtime. -f, --rtc=filename Overrides the default /dev file name, which is /dev/rtc on many platforms but Herbert, how does this work, and is the same method applicable to x86_64?
Sharepoint 2013: Rest API - does header need to include X-RequestDigest? It's ok that without root I get this messages? When > I'm at the command prompt, /dev/rtc exists. No Usable Clock Interface Found. You can always override this value with options on the hwclock command line.
It may be more effective to simply track the System Clock drift with sntp, or date -Ins and a precision timepiece, and then calculate the correction manually. Agreed? hwclock --hctosys also uses the adjtime file data to compensate the value read from the Hardware Clock before using it to set the System Clock. https://bugs.launchpad.net/bugs/8414 modprobe rtc-cmos Without rebooting, try and access the clock again with the hwclock command.
Cannot access the Hardware Clock via any known method. How do I make an alien technology feel alien? Removing the first call stops the error message and the second call works fine. Blog Linux user number: 433157 - Member of Cypriot, Serbian, Greek LoCos Brainstorm: Official end-of-life dates list, Kernel boot parameter to disable modules, End-of-Life?
ENVIRONMENT TZ If this variable is set its value takes precedence over the system configured timezone. http://serverfault.com/questions/39356/why-is-the-time-messed-up-on-my-ubuntu-server-vps GBiz is too!

I'm on a Tyan K8W and I'm seein the same thing. navigate here This second field is not used under Linux and is always zero. Setting to BST returns: Current default timezone: 'Europe/London'Local time is now: Sat Jul 11 22:03:02 BST 2009.Universal Time is now: Sat Jul 11 21:03:02 UTC 2009. See the --getepoch option for details. --predict Predict what the RTC will read at time given by the --date option based on the adjtime file. Cannot Access The Hardware Clock Via Any Known Method. + Linux
You'll just make a mess. Linux handles daylight saving time changes transparently only when the Hardware Clock is kept in the UTC timescale. Note: currently this is not possible on most systems because hwclock --systohc is called at shutdown.
Though hwclock ignores the year value when it reads the Hardware Clock, it sets the year value when it sets the clock. TZDIR If this variable is set its value takes precedence over the system configured timezone database directory path. It seems it's not possible to detect the RTC through hotplug (it's not a PCI device), and we don't have time to implement another solution for warty. You can use an adjtime file that was previously used with the clock(8) program with hwclock.
For example, if you are using the convention that the year counter in your Hardware Clock contains the number of full years since 1952, then the kernel's Hardware Clock epoch value If you specify neither --utc nor --localtime, the default is whichever was specified the last time hwclock was used to set the clock (i.e. A better choice for manual configuration would be adjtimex's --log options. this contact form If the adjtime file doesn't exist, the default is UTC.
This problem can be avoided when configuring drift correction for the System Clock by simply not shutting down the machine. You can also use the program adjtimex(8) to smoothly adjust the System Time while the system runs. Suppose you start with no adjtime file. It then records the current time as the last time the clock was adjusted.
It is important that the System Time not have any discontinuities such as would happen if you used the date(1) program to set it while the system is running. POSIX systems, like Linux, are designed to have the System Clock operate in the UTC timescale. On an ISA system, hwclock can directly access the "CMOS memory" registers that constitute the clock, by doing I/O to Ports 0x70 and 0x71. Otherwise, it is off.
Another 24 hours go by and you issue another hwclock --adjust. Hardware Clock Access Methods hwclock uses many different ways to get and set Hardware Clock values. To configure a system to use a particular database all of the files located in its directory must be copied to the root of /usr/share/zoneinfo. There are three of them: 1.
Also, if something has changed the Hardware Clock, like NTP's '11 minute mode', then --hctosys will set the time incorrectly by including drift compensation.
