Daily Challenge #290 - Read the Time

#challenge

Given time in 24-hour format, convert it to words.

For example: 13:00 = one o'clock 13:09 = nine minutes past one 13:15 = quarter past one 13:29 = twenty nine minutes past one 13:30 = half past one 13:31 = twenty nine minutes to two 13:45 = quarter to two 00:48 = twelve minutes to one 00:08 = eight minutes past midnight 12:00 = twelve o'clock 00:00 = midnight Note: If minutes == 0, use 'o'clock'. If minutes <= 30, use 'past', and for minutes > 30, use 'to'. Good luck!

Tests:

07:01
01:59
12:01
00:01
11:31
23:31
