How to modify the time of UbuntuLinux

Article Title: how to modify the UbuntuLinux time. Linux is a technology channel of the IT lab in China. Including desktop applications, Linux system management, kernel research, embedded systems, open source, and other basic classification of UTC is Greenwich Mean Time, CST is China Standard Time, obviously CST = UTC + 8.

Based on this, if your CMOS is local time (that is, CST time) and you want to use local time, you need to make the following modifications:

Shell> sudo vim/etc/default/rcS (locate the utc settings)

# Utc = yes # comment out and change it to no

Utc = no # Save and exit

If your local time is not accurate, you can modify it as follows:

Shell> sudo date-s MM/DD/YY

Shell> sudo date-s hh: mm

Shell> sudo/etc/init. d/hwclock. sh restart # Write the modified time to the cmos

When a command is executed during modification, the system prompts that the modification is too early in the future.

Note: After the instance is restarted, modify it.
