Extracting Current Time with Millisecond Precision in Java

To obtain the current time in the format YYYY-MM-DD HH:MI:Sec.Millisecond, an extension to the provided code is necessary. The crux of the modification lies in refining the SimpleDateFormat pattern.

The code provided retrieves the current time without millisecond information:

public static String getCurrentTimeStamp() {
    SimpleDateFormat sdfDate = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
    Date now = new Date();
    String strDate = sdfDate.format(now);
    return strDate;
}

To append millisecond data, a modified date format is applied:

SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSS");

The additional ".SSS" signifies the placement of milliseconds. The resulting format grants access to timestamp data with millisecond precision.

For instance, a timestamp in the format YYYY-MM-DD HH:MM:SS (2009-09-22 16:47:08) can be transformed to incorporate milliseconds (2009-09-22 16:47:08.128). This enhanced time representation caters to applications requiring granular temporal accuracy.
