Changing the Linux server date to future

James0806 · 07-17-2018, 06:34 PM

Hi,

I have tried changing the date of the linnux machine to past which is happening but not to the future

Code:

date -s "19 APR 2012 11:14:00"

with the above command we can set it to that date but i want it to be for the year 2019

it is just displays when i replace 2012 with 2019 and later it is to the current date and time

There's a good chance the machine is set to sync from a time server in the internet.

Whyever would you want to do this?

The ntp service was disabled and as said we could change the date to past date but not to the future date.
I wanted to change it to the year 2019

Are you saying that it just doesn't happen and you receive no error when you issue the command?

Because I do that on systems that have no real time clock nor NTP service.

You set the date. And since every date from 00:01 1/1/1900 is a future date, it just works.

Maybe you could try setting it in the bios.

I think AwesomeMachine is onto something. After you set the software date, try running

Code:

hwclock -w

and let us know what happens.

From the man page for hwclock:

Quote:

-w, --systohc
Set the Hardware Clock from the System Clock, and update the timestamps in /etc/adjtime. When the --update-drift option is given, then also (re)calculate the drift factor.
