I'm trying to save my TimeGroupDataset to a file. I used the code below:

CSV csv = new CSV();
csv.setTimeDateFormat(new SimpleDateFormat ("dd-MMM-yyyy HH:mm"));
dataset.writeGroupDataset(csv, "output.csv");

The output.csv file is created but the dates in the file aren't formatted. The dates are just numbers expressed in scientific notation like: 1.23628296E12.

a) Is this how dates are supposed to be output to the csv file?

b) When I try to create a new TimeGroupDataset using the output file produced above and the same CSV instance I get incorrect results because all the dates in the new TimeGroupDataset are 0.

What am I doing wrong?

You should be using writeTimeSimpleDataset and readTimeSimpleDataset.

csv.setTimeDateFormat(new SimpleDateFormat ("dd-MMM-yyyy HH:mm"));


Dataset1.writeTimeSimpleDataset(csv, "c:\\SimpleBar.csv");

Dataset1.readTimeSimpleDataset(csv, "c:\\SimpleBar.csv",0,0);
