How to convert timestamp string to epoch time?

Question

I have time stamp in format 2017-18-08 11:45:30.345.
I want to convert it to epoch time, so I am doing below:

String timeDateStr = \"2017         


        

Answer 1

Corrected your code regarding yyyy-dd-MM. Also minute value could be 1-59 not 60. You provided 60. This is another simple way to solve the issue. Simply use DateFormat class.

String timeDateStr = "2017-18-08 12:59:30.345";
DateFormat df = new SimpleDateFormat("yyyy-dd-MM hh:mm:ss.SSS", Locale.ENGLISH);
try {
    Date d = df.parse(timeDateStr);
    System.out.println(d.toInstant().toEpochMilli());
} catch (ParseException e) {
    e.printStackTrace();
}
