Answer 1

Before the line buf.append(text); add this lines of code;

SimpleDateFormat sdf = new SimpleDateFormat("HH:mm dd/MM/yyyy");
String currentDateandTime = sdf.format(new Date());
text+=" "+currentDateandTime;

Answer 2

SimpleDateFormat dateFormat = new SimpleDateFormat("d/M/yyyy");
SimpleDateFormat timeFormat = new SimpleDateFormat("hh:mmz");

here is the code to generate single statement, I assuming that you using Location object

13.01471695,80.1469223 time:12 30pm date:1/1/2013

Date locationDate = new Date(location.getTime());

StringBuilder sb = new StringBuilder(location.getLatitude())
.append(",")
.append(location.getLongitude())
.append("time:")
.append(timeFormat.format(locationDate))
.append(" date:")
.append(dateFormat.format(locationDate));

String locationDetail = sb.toString();

Why not use a an SQLiteDatabase for this then you can simply use something like this to insert records with the current date time:
