I need to filter by time, I thought it would be like this:

$humans = await alles.filter(all => all.last_seen.time > (time() - $1day))

const date = new Date();
const time = Math.floor(date.getTime() / 1000);
const $1day = 24 * 60 * 60;
const filtered = array.filter(entry => {
  if (entry.hasOwnProperty('last_seen')) {
    return entry.last_seen.time > (time - $1day);
  }
  return false;
});
