Q. How can I set the system date and time from the command prompt (bash shell)? I don't have GUI installed and I am login over ssh session.
A. Use date command to display the current date and time or set the system date / time over ssh session.
This is useful if the Linux server time and/or date is wrong, and you need to set it to new values from the shell prompt.
You must login as root user to use date command.
Linux Set Date
Use the following syntax to set new data and time:
date set="STRING"
For example, set new data to 2 Oct 2006 18:00:00, type the following command as root user:
# date -s "2 OCT 2006 18:00:00"
OR
# date set="2 OCT 2006 18:00:00"
You can also simplify format using following syntax:
# date +%Y%m%d -s "20081128"
Linux Set Time
To set time use the following syntax:
# date +%T -s "10:13:13"
Where,
- 10: Hour (hh)
- 13: Minute (mm)
- 30: Second (ss)
Use %p locale’s equivalent of either AM or PM, enter:
# date +%T%p -s "6:10:30AM"
# date +%T%p -s "12:10:30PM"

Do check and sync hardware clock with:
# hwclock –show
# hwclock –systohc
This configuration string is exactly what i’m searching for. thanks.
i had to set the date by using {date -s “wed jul 30 19:41:00 BST 2008″} while at the root.
hey thanks a million,

You could also simplify the format of input date as example below
date +%Y%m%d -s "20080817"(set new date to August 17, 2008) without typing full date formatJust amazing command… & help.. gr88 work.. keep it up.
May allah bless you…
thank you!!!!
i have fedora 9 i can not change the time using his time control application. he ask for my root password, and then he says that it is not correct…. crazy program :)
the man page of date did not showed me any example, i what i tried was not accepted.
thank you.
Thanks
this is gr8
I synced HW clk with sysstem clock also.
But after reboot the time is again changed
The man page for the ‘date’ command is WORTHLESS.
Now that I read here how to format the input string in order to set the clock my life is good. THANK YOU!
thanks !
very nice article, super easy :)
Thanks brother,
It has worked. Great work…!
date set=”2 OCT 2006 18:00:00″
it is doesn’t work.
I have to change my linux system time./ Right now it is shows correct time on my machine but when i open my gmail account it’s shows wrong time of my emails.Due to it’s system time.
Any idea?
Anyone has ideas how to set Dates 1 day or 2 dates ago. What about setting it +2 hours in advance etc ?
Hi All,
The problem I’m having is, the time/date changes at the time I do it, but doesn’t hold after a reboot – how can i lock it into the Server’s clock..
Neelesh – Try date -s ”2 OCT 2006 18:00:00″ instead
Nickalf. . .
Thanx alot.. working properly
date -s ”2 OCT 2006 18:00:00″ is set for the time being. Need o set CMOS clock using “hwclock” command. That will be right solution.
SIDE NOTE RE: SETTING HWCLOCK
format should be:
# hwclock –systohc
(note double -)
CHeers!
Thanks alot
THis has worked like yesterday
Keep up the good work.

Dear Sir,
Thanks a Lot.

Thanks!!!
One more thank you for your simple explanation and great example. I couldn’t figure out the format from reading the date man page.
Nice
Thank you so much, it works.
Thank you! This information was very helpful.
Some of the examples you have presented here would be hard to derive from the
dateman page.
