how to get a formatted date as milliseconds?

Question

I have a formatted date from sqllite database, to use this in a graph view I need to format it in a long number.

The format is:

2012-07-11 10:55:21

how can I convert it to milliseconds?

Solution 1

You can convert the string into a Date object using this code:-

Date d = DateFormat.parse(String s)

And then convert it into milliseconds by using the inbuilt method

long millisec = d.getTime();

Solution 2

Use date.getTime()

SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd, HH:mm:ss");
formatter.setLenient(false);


String oldTime = "2012-07-11 10:55:21";
Date oldDate = formatter.parse(oldTime);
long oldMillis = oldDate.getTime();
