I'm trying to create a zoo object from a tick data file(sample below) which
contains timestamps only.
Filename: "20080202.trd"
1|BHARTIARTL|EQ|18:15:05|600|1
2|BHARTIARTL|EQ|18:15:05|600|99
3|GLENMARK|EQ|18:15:05|238.1|5
4|HINDALCO|EQ|18:15:05|43.75|100
5|BHARTIARTL|EQ|18:15:05|600|1
6|BHEL|EQ|18:15:05|1100|11
7|HINDALCO|EQ|18:15:06|43.2|1
8|CHAMBLFERT|EQ|18:15:06|46|10
9|CHAMBLFERT|EQ|18:15:06|46|90
10|BAJAUTOFIN|EQ|18:15:06|80|100

As you can see that timestamps are not unique even at microsecond levels.
Inorder to create a zoo/xts object to be used with quantmod later, How do
I:-
1)Do I have to merge two rows with the same timestamp, symbols, price but
different volumes.(Do I need to do this or is there some other way possible)
2)Append date to the timestamp while creating the zoo/xts object

I'm trying to explore the 'format' argument, and POSIX and chron but without
much success.

Thanks
