How do I read a Unix timestamp?

How do I find microseconds in Unix?
date +%s%N returns the number of seconds + current nanoseconds. Therefore, echo $(($(date +%s%N)/1000000)) is what you need.
…
- %N” returns the current time with nanoseconds. …
- %6N” returns the current time with nanoseconds rounded to the first 6 digits, which is microseconds.
What is current timestamp?
