sql - mysql group by and sort each group

I have the following table:

ID NAME TIME
1  A    0
2  A    3
3  B    1

I am using the query below which produces:

SELECT * FROM `table` GROUP BY `NAME`
ID NAME TIME
1  A    0
3  B    1

And I want use GROUP BY to generate a result like this (discount sort by the TIME column):

ID NAME TIME
2  A    3
3  B    1
