Tell HN: Hacker News datetimes are falsely precise

I just noticed that the datetime for comments and submissions is weirdly precise. Apparently all comments happen exactly on the second, to the microsecond!

e.g. here is one from a few minutes ago: 2026-09-10T14:50:13.000000Z

This is a clear example of false precision:

    Indeed, it is also imprecise since the timestamp does't include the timezone. :)

      Z means Zero Time (+00:00). They're UTC timestamps
