Gets the Unix timestamp from a Date object

• Use new Date() to get the Date object and Date.prototype.getTime() to get the timestamp in milliseconds and divide by 1000 to get the timestamp in seconds.
• Use Math.floor() to appropriately round the resulting timestamp to an integer.

const getTimestamp = date =>
  Math.floor(date.getTime()/1000);

getTimestamp(new Date()); // 1602162242
