@summary Convert the given argument to an instance of Date.

@description
Convert the given argument to an instance of Date.

If the argument is an instance of Date, the function returns its clone.

If the argument is a number, it is treated as a timestamp.

If the argument is none of the above, the function returns Invalid Date.

**Note**: *all* Date arguments passed to any *date-fns* function is processed by `toDate`.

@param {Date|Number} argument - the value to convert
@returns {Date} the parsed date in the local time zone
@throws {TypeError} 1 argument required

@example
// Clone the date:
const result = toDate(new Date(2014, 1, 11, 11, 30, 30))
//=> Tue Feb 11 2014 11:30:30

@example
// Convert the timestamp to date:
const result = toDate(1392098430000)
//=> Tue Feb 11 2014 11:30:30
