  • 0

I have two Linux (CentOS 6.0) machines over here and I need to add (or remove) 5 seconds to the current date time. In the end, both my machines would have a gap of 5 seconds (one with the right time and the other one with 5 seconds more or less).

I know I can change the date with this command:

date -s "DD MMM YYYY HH:MM:SS"

but I need to be precise and it will be hard for me to run the command at the right time.

So I’d like to know if there is a way in general to add 5 seconds to the current time, a bit like when you choose your time zone compared to Greenwich (+5 hours in my case).

    You can add 5 seconds to the current time in one command using date -s "5 seconds".

    The full manual regarding all of the date input formats that all of GNU coreutils accepts can be found online at https://www.gnu.org/software/coreutils/manual/html_node/Date-input-formats.html.
