Linux – How to retrieve the current time on a server

date timelinux

I want to know the time on a server accurate to the millisecond.

there's this way:

local $ ssh user@servername
Welcome to server!
server $ date
Fri Feb 18 11:27:50 EST 2011

But I need more accuracy. Is there a command that will be more precise?

Check " man date ". You can let it display you the hours, minutes, seconds and nanoseconds with 

date +%H:%M:%S.%N

See the output of

while : ; do date +%H:%M:%S.%N ; done

interrupt the infinite while loop with CTRL+C .

If you want less decimal places you could do

while : ; do date +%H:%M:%S.%N | cut -c 1-12 ; done

Increase or decrease the output length changing the "12" on "-c 1-12" after cut.
