[Solved] Time in milliseconds calculation

by


Here some tipps to get started:

You can parse the String to a Java Date like this:

SimpleDateFormat format = new SimpleDateFormat("HH:mm:ss");
Date startTimer1Date = format.parse(StartTimer1);

You can get the current Date and Time like this:

Date dateNow = new Date();

And since you are working with time only (and not with date and time), you will need to manipulate the Date, Month and Year of all values to a common base, e.g. : 

Calendar c = Calendar.getInstance();
c.setTime(dateNow);
c.set(Calendar.YEAR, 1970);
c.set(Calendar.DAY_OF_YEAR, 1);
dateNow = c.getTime();
