The following are ways of telling the time in Chinese:
A: 現在幾點﹖
B: 現在...
兩點 2:00
十點半 (or 十點三十分) 10:30
三點一刻 (or 三點十五分) 3:15
十二點三刻 (or 十二點四十五分) 12:45
兩點差五分 (or 差五分兩點) 1:55
五點二十分 5:20
六點零五分 6:05
七點三十五分 7:35
Some notes:
When zero is flanked by two digits, it is normally read as 零, as in 三點零八分 (3:08) or 十二點零三分 (12:03).
When the minutes are greater than 10, the word 分 is optional:
七點十五 or 七點十五分
"This morning" is 今天上午, not for example 這個上午; "every afternoon" is 每天下午, not 每下午.
