您已经为JSpinner定义了两件事（基本上是本教程的内容完全回答了您的问题）
SimpleDateFormat
SpinnerDateModel
例如
import java.awt.*;import java.text.SimpleDateFormat;import java.util.*;import javax.swing.*;import javax.swing.event.*;public class TimeZoneSpinners { private final String[] zones = {"Asia/Tokyo", "Asia/Hong_Kong", "Asia/Calcutta", "Europe/Paris", "Europe/London", "America/New_York", "America/Los_Angeles" }; private final JLabel[] labels = new JLabel[zones.length]; private final SimpleDateFormat[] formats = new SimpleDateFormat[zones.length]; private JSpinner spinner; private SpinnerDateModel model; private SimpleDateFormat format; private JPanel panel; private Jframe frame = new Jframe(); public void makeUI() { Calendar cal = Calendar.getInstance(); Date date = cal.getTime(); model = new SpinnerDateModel(); model.setValue(date); spinner = new JSpinner(model); spinner.addChangeListener(new ChangeListener() { @Override public void stateChanged(ChangeEvent e) { Date date = (Date) ((JSpinner) e.getSource()).getValue(); for (int i = 0; i < labels.length; i++) { labels[i].setText(formats[i].format(date)); } } }); format = ((JSpinner.DateEditor) spinner.getEditor()).getFormat(); format.setTimeZone(TimeZone.getTimeZone(zones[0])); format.applyPattern("yyyy-MM-dd HH:mm:ss"); panel = new JPanel(new GridLayout(zones.length, 2, 10, 10)); for (int i = 0; i < zones.length; i++) { formats[i] = new SimpleDateFormat("yyyy-MMM-dd HH:mm:ss"); formats[i].setTimeZone(TimeZone.getTimeZone(zones[i])); JLabel label = new JLabel(zones[i]); labels[i] = new JLabel(formats[i].format(date)); panel.add(label); panel.add(labels[i]); } frame.setLayout(new BorderLayout(10, 10)); frame.add(spinner, BorderLayout.NORTH); frame.add(panel, BorderLayout.CENTER); frame.setDefaultCloseOperation(Jframe.EXIT_ON_CLOSE); frame.pack(); frame.setVisible(true); } public static void main(String[] args) { SwingUtilities.invokeLater(new Runnable() { @Override public void run() { new TimeZoneSpinners().makeUI(); } }); }}
