There is a question with two answers from two different users that have the same time stamp:



Is the time stamp actually accurate to the millisecond?

    The displayed timestamp only has a precision of 1 second. Why would you expect millisecond accuracy? Commented Sep 21, 2017 at 6:36

Yes, millisecond values exist, but are not shown directly on the site

Using Stack Exchange Data Explorer (SEDE), I've written a small query to demonstrate that the millisecond value exists. The 'CreatedDate' field will not show this by default, but by CONVERT()ing the field and using the '114' datetime style (hh:mi:ss:mmm) we can see the milliseconds:

Example returned values

Do note that the data displayed on SEDE is only refreshed once a week, so your example answers won't appear until next Monday. We'll have to wait and see what the milliseconds look like. Note however, that based on the Answer IDs in your above links:

  • 318493 - Timmy Jim
  • 318494 - Avery

Timmy Jim was 'first' :)

  • 6
    Alright, the SEDE numbers are here. Timmy Jim's answer preceded mine by merely 44 msecs. That's crazy.
