+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.
