And then we divide that by 1000 to get the number of seconds since epoch.
For instance, we write
const d = new Date();
const seconds = d.getTime() / 1000;
to create the date d.
And then we call d.getTime to return the timestamp in milliseconds.
Then we divide that by 1000 to get the number of seconds since epoch.
