Learning how to read time

Hahaha, according to I'm not good at English. I need more practices :D. So, this time I found the website that contains the speakable application to teach me how to tell the time. It's very easy to follow. The link is here: http://www.timemonsters.com/.

There are 2 ways to read time. The first one is to read hours then minutes. Another is telling how long it past then hours for the first half , and telling the remaining minutes left then next hours for the latter half.

Examples:
4:00    ->    Four o' clock
4:05    ->    Four - oh - five, Five past four
4:15    ->    Four fifteen, A quarter past four
4.30    ->    Four thirty, Half past four
4.45    ->    Four forty-five, A quarter to five
4.50    ->    Four fifty, Ten to five
