Blue Bridge Cup VIP Time Report Assistant

Problem Description

Given the current time, please read it out in English.
　　Time is expressed in hours h and minutes m. In English reading, the way to read a time is:
　　if m is 0, then read the time, then add "o'clock", such as 3:00 read "three" o'clock ".
　　If m is not 0, then read out the time, and then read out the points, such as 5:30 read "five thirty"
　　Hours and minutes are pronounced in English numerals, 0-20 is pronounced as:
　　0: zero, 1: one, 2: two, 3: three, 4: four, 5: five, 6: six, 7: seven, 8: eight, 9: nine, 10: ten, 11: eleven, 12: twelve, 13: thirteen, 14: fourteen, 15: fifteen, 16: sixteen, 17: seventeen, 18: eighteen, 19: nineteen, 20: twenty.
　　30 is pronounced thirty, 40 is forty, and 50 is fifty.
　　For numbers greater than 20 and less than 60, first read the whole ten, then add the single digits. For example, 31 first reads 30 and then adds 1, which is read as "thirty one".
　　According to the above rule, 21:54 reads "twenty one fifty four", 9:07 reads "nine seven", and 0:15 reads "zero fifteen".
