please i would like to know how to stop changing time in windows 7? I am using dual boot

Windows assumes the hardware clock on the computer is local time and uses it directly.
Linux assumes the hardware clock is UTC and applies an offset to get local time.

Check what linux is doing by opening a terminal and typing

Code:

timedatectl

You can make Linux use local time (like windows does) by setting

Code:

timedatectl set-local-rtc 1 --adjust-system-clock

Then both OS will interpret the hardware clock as local

timedetectl not found

[stevef]

The actual command is

Code:

timedatectl

Your screenshot shows "timedetectl" which the system didn't like.

timedatectl set-local-rtc 1 --adjust-system-clock
