+Gets the Unix timestamp from a `Date` object.
+
+- Use `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.
+- Omit the argument, `date`, to use the current date.
+
+```js
+const getTimestamp = (date = new Date()) => Math.floor(date.getTime() / 1000);
+```
+
+```js
+getTimestamp(); // 1602162242
+```
