时间和日期类（III）

Input
输入的第一个整数n，表示有n组测试数据。
后面的输入每行为一组测试数据。每组测试数据的前3个整数是日期的年月日，后3个整数是时间的时分秒。

Output
每组测试数据对应一行输出。日期的输出格式为“yyyy-mm-dd”，时间的输出格式为“hh:mm:ss”，中间用一个空格分开。

Sample Input
3
1982 10 1 0 0 0
2000 2 28 23 59 59
2014 7 2 13 30 01

Sample Output
CREATE Time : (0, 0, 0)
CREATE Date : (1, 1, 1)
CREATE DateTime : (1, 1, 1, 0, 0, 0)
0001-01-01 00:00:00
1982-10-01 00:00:00
2000-02-28 23:59:59
2014-07-02 13:30:01

HINT
输出格式用头文件中流操作算子：
setw(w) ：设置数据的输出宽度为w个字符
setfill(c)：设置用字符c作为填充字符
