Linux permanently modifies the system time and time zone method

Modify Time Zone :

1>

Locate the appropriate time zone file/usr/share/zoneinfo/asia/shanghai

Replace the current/etc/localtime file with this file.

Or find a server that you think is standard time, and then

#scp [Email Protected]:/etc/localtime/etc/localtime

2>

Modify the/etc/sysconfig/clock file to:

Zone= "Asia/shanghai"

Utc=false

Arc=false

Temporary method:

tz= ' Asia/shanghai ';

Export TZ

Modified Date Time :

1>

Modify Date Time with date

#date-S 08/24/2006

#date-S 13:02:00

2>

Synchronous BIOS clock, forcing system time to be written to CMOS

#clock-W

Also, view Bois time with #hwclock-R

Linux modifies the system time zone

1. View the current time zone

# Vi/etc/sysconfig/clock

2. Modify the settings time zone

Method (1) # Tzselect Method (2 limited to Redhat Linux and CentOS) # Timeconfig

3. Copy the appropriate time zone file and replace the system default time zone

# cp/usr/share/zoneinfo/$ main time zone/$ times time zone/etc/localtime for Chinese servers execute: # cp/usr/share/zoneinfo/asia/shanghai/etc/localtime

4. Write the current time to the BIOS for permanent use (avoid failure after reboot)

# Hwclock
