Command to get time in milliseconds

Question

Is there a shell command in Linux to get the time in milliseconds?

Answer 1

• date +"%T.%N" returns the current time with nanoseconds.

  06:46:41.431857000
  

• date +"%T.%6N" returns the current time with nanoseconds rounded to the first 6 digits, which is microseconds.

  06:47:07.183172
  

• date +"%T.%3N" returns the current time with nanoseconds rounded to the first 3 digits, which is milliseconds.

  06:47:42.773
  

In general, every field of the date command's format can be given an optional field width.
