Setting Your System's Time
Occasionally some users have the need to reset their Manjaro system's time/date. This is quite an easy process involving a few steps at the command line (for those unfamiliar with the command line see the section above this one).
Check your system's time/date settings
The following command:
[handy@jarmano ~]$ timedatectl status
Gives this output on my machine:
[handy@jarmano ~]$ timedatectl status
Local time: Mon 2013-07-08 10:21:32 WST
Universal time: Mon 2013-07-08 00:21:32 UTC
RTC time: Mon 2013-07-08 00:21:32
Timezone: Australia/Perth (WST, +800)
NTP enabled: no
NTP synchronized: no
RTC in local TZ: no
DST active: no
Last DST change: DST ended at
Sun 2013-04-07 02:59:59 WST
Sun 2013-04-07 02:00:00 WST
Next DST change: DST begins (the clock jumps one hour forward) at
Sun 2013-10-06 01:59:59 WST
Sun 2013-10-06 03:00:00 WST
The above output has the wrong Timezone, & NTP not enabled. If the output on your machine does NOT have the correct Timezone: &/or has NTP enabled: no then continue & we'll fix those problems up.
Turn on the Network Time Protocol (NTP) [1]
First off we had better be sure that even though the ntp package is installed by default on the Manjaro system, it is actually there, if it is already there this will do no harm:
[handy@jarmano ~]$ sudo pacman -S ntp
Now we can turn on ntp on by using the following command in the Terminal (sudo requires the root password):
[handy@jarmano ~]$ sudo timedatectl set-ntp true
List Supported Timezones (locales)
The following command lists the supported timezones:
[handy@jarmano ~]$ timedatectl list-timezones
Scroll through this list (use the space bar to move to the next page) to find yours, then use your mouse to highlight it & then copy it using the Terminal's menu or the keyboard shortcuts (Ctrl, Shift & C). Typing q at any time will return you to the Terminal prompt.
Set the Correct Timezone
Now that you have your timezone copied to the clipboard, we need to tell the system to use it. We do that with the following command (requires root password), this example uses my timezone of Australia/Sydney:
[handy@jarmano ~]$ sudo timedatectl set-timezone Australia/Sydney
Verify that your Timezone (time & date) & NTP are working
To verify that your input has worked enter the following command:
[handy@jarmano ~]$ timedatectl status
Local time: Mon 2013-07-08 10:21:32 EST
Universal time: Mon 2013-07-08 00:21:32 UTC
RTC time: Mon 2013-07-08 00:21:32
Timezone: Australia/Sydney (EST, +1000)
NTP enabled: yes
NTP synchronized: yes
RTC in local TZ: no
DST active: no
Last DST change: DST ended at
Sun 2013-04-07 02:59:59 EST
Sun 2013-04-07 02:00:00 EST
Next DST change: DST begins (the clock jumps one hour forward) at
Sun 2013-10-06 01:59:59 EST
Sun 2013-10-06 03:00:00 EST
You should now see the Timezone:
Set the System Time
For those that have a need to set the system's clock directly, use the following command:
[handy@jarmano ~]$ sudo timedatectl set-time "2013-08-11 23:56:16"
If you still have problems please post in this Manjaro forum thread: [2]
