If all data columns in the file share a common time stamp, the file can have the following format:
"Val1", "Val2", "_time",
10.75,1,9/19/95 8:32:00
10.83,2,9/19/95 8:33:00
The first line consists of the column names enclosed in double quotes, and separated by the International settings list separator (in this case, a comma). The column that designates the time stamp must be labeled "_time". The rows following the column names are the rows of data.
