Windows time utc

I've also tried instructing it not to set time automatically which I think I may have done in Windows 7? Has anyone had any success in using UTC time in Windows 10 and if so was it necessary to do anything differently compared to Windows 7?

It is not necessary to hack the ms-windows registry that I have done many times. The real problem is that ms-windows does not sync the clock at startup as Linux does.

The following sets the hardware clock from the system clock. See hwclock 8 section "The Adjtime File" for more information on this file as well as the Time skew section. The system clock a. After boot-up has completed, the system clock runs independently of the hardware clock.

The Linux kernel keeps track of the system clock by counting timer interrupts. The localtime standard is dependent on the current time zone , while UTC is the global time standard and is independent of time zone values. If multiple operating systems are installed on a machine, they will all derive the current time from the same hardware clock: it is recommended to adopt a unique standard for the hardware clock to avoid conflicts across systems and set it to UTC.

The hardware clock can be queried and set with the timedatectl command. You can see the current hardware clock time standard of the Arch system using:. During kernel startup, at the point when the RTC driver is loaded, the system clock may be set from the hardware clock. Whether this occurs depends on the hardware platform, the version of the kernel and kernel build options.

Hence, having the hardware clock using localtime may cause some unexpected behavior during the boot sequence; e. To avoid it systemd will only synchronize back , if the hardware clock is set to UTC and keep the kernel uninformed about the local timezone. Windows by default uses localtime [1].

It can be done by a simple registry fix: Open regedit and add a DWORD value with hexadecimal value 1 to the registry:. You should also check with your logging and firewall vendors to see what they recommend for selection of time. Often applications choose a time zone for you. Hallam-Baker and Brian Behlendorf. You had to make an adjustment if you wanted a local time zone. Often in forensics, you use the registry to determine what time zone a computer is located in.

Older SQL applications often were written without cloud platforms in mind and using local time. Before migrating applications to the cloud, evaluate if they can handle a transition to UTC time.

Finally, you can use PowerShell to determine the exact time zone of the computer and use it to determine the time zone from a series of remote computers. The command Get-TimeZone will respond with the time zone of the computer.

It can be combined with a list of servers to determine the time zone of numerous systems. Show 5 more comments. The Overflow Blog.
