How to parse .NET DateTime Ticks value in Java

I had to consume an XML data that contains .NET DateTime Ticks (long type) value. This should do it.


import java.util.*;

public class DotNetTicksUtil 
{
  
    private static final long TICKS_AT_EPOCH = 621355968000000000L;
    private static final long TICKS_PER_MILLISECOND = 10000;

    /**
     * Given a .NET ticks value, we convert it to Java's Calendar object.
     * Conversion may not be perfectly precise, so do expect some margin of errors.
     */
    public static Calendar toCalender(long ticks) 
    {
        //long ticks = 634200192000000000L;

        Date date = new Date((ticks - TICKS_AT_EPOCH) / TICKS_PER_MILLISECOND);
        System.out.println(date);

        TimeZone utc = TimeZone.getTimeZone("UTC");
        Calendar calendar = Calendar.getInstance(utc);
        calendar.setTime(date);
        return calendar;
    }
}
