 * Format seconds as a duration string.

 * - HH:MM:SS (> 1 hour)
 * - MM:SS:MSS (`displayMilliseconds = true`)
 * - MM:SS (`displayMilliseconds = false`)

 * Supplying a guide (in seconds) will force a number of leading zeros
 * to cover the length of the guide.

 *     string.
 * @param {number} guide - Number (in seconds) to model the string after.
 * @param {boolean} displayMilliseconds - Display milliseconds or not.
 * @return {string} Formatted duration time, e.g '00:12:653'.
