3+ * Human readable duration format 转换时间格式
4+ * Your task in order to complete this Kata is to write a function which formats a duration, given as a number of seconds, in a human-friendly way.
5+ * The function must accept a non-negative integer. If it is zero, it just returns "now". Otherwise,
6+ * the duration is expressed as a combination of years, days, hours, minutes and seconds.
7+ * formatDuration(62) // returns "1 minute and 2 seconds"
8+ * formatDuration(3662) // returns "1 hour, 1 minute and 2 seconds"
