在序列化和反序列化java.util.Date时，PortableObjectSerializer不准1秒

Question

对于下面的代码，我注意到~1秒的差异（序列化前的长时间= 1298298092890;反序列化后的长时间= 1298298093432）

public void readExternal(PofReader pReader) throws IOException {
    //...0 to 8 omitted for brevity
    tradeTimestamp =pReader.readDate(9);
    entryTimestamp = pReader.readDate(10);
}

public void writeExternal(PofWriter pWriter) throws IOException {
        //...0 to 8 omitted for brevity
    pWriter.writeDate(9,tradeTimestamp);
    pWriter.writeDate(10,entryTimestamp);

}

Answer 1

根据API，writeDate的精度有限。请改用writeDateTime
