Get time in millis using Calendar

This is an example of how to get the time in millis, using the abstract Calendar class, that provides methods for converting between a specific instant in time and a set of calendar fields such as YEAR, MONTH, DAY_OF_MONTH, HOUR. Getting the time in milliseconds with Calendar implies that you should:

  • Use getInstance() API method of Calendar, in order to get a Calendar object, using the default time zone and locale.
  • Use getTimeInMillis() API method of Calendar, to get this Calendar’s time value in milliseconds.

Let’s take a look at the code snippet that follows:

package com.javacodegeeks.snippets.core;

import java.util.Calendar;

public class GetTimeInMillisUsingCalendar {
	
	public static void main(String[] args) {
		
		Calendar c = Calendar.getInstance();
		 
		long millis = c.getTimeInMillis();
		
		System.out.println("Milliseconds since Jan 1, 1970: " + millis);
		
	}

}

Output:

Milliseconds since Jan 1, 1970: 1319055073487
