EVALUATION

The following code in ZipFileIndex looks "suspicious"

        // From java.util.zip
        private static long dosToJavaTime(int nativetime) {
            // Bootstrap build problems prevent me from using the code directly
            // Convert the raw/native time to a long for now
            return (long)nativetime;
        }
                                     

EVALUATION

For reference, here is the relevant code from dosToJavaTime in java.util.Zip

    /*
     * Converts DOS time to Java time (number of milliseconds since epoch).
     */
    private static long dosToJavaTime(long dtime) {
	Date d = new Date((int)(((dtime >> 25) & 0x7f) + 80),
			  (int)(((dtime >> 21) & 0x0f) - 1),
			  (int)((dtime >> 16) & 0x1f),
			  (int)((dtime >> 11) & 0x1f),
			  (int)((dtime >> 5) & 0x3f),
			  (int)((dtime << 1) & 0x3e));
	return d.getTime();
    }

Note however, this code uses a deprecated Date constructor, with the following comment
     * @deprecated As of JDK version 1.1,
     * replaced by <code>Calendar.set(year + 1900, month, date,
     * hrs, min, sec)</code> or <code>GregorianCalendar(year + 1900,
     * month, date, hrs, min, sec)</code>.
