您可以从日期中仅提取想要的部分作为输入值。

$(()=>{
  let lastFocusEl = null;
  
  $('#time').on('click', e => {
    if (!lastFocusEl) return;

    let time = new Date();
      
    // pull off just the parts you want into the value
    lastFocusEl.value = `${time.getHours()}:${time.getMinutes()}:${time.getSeconds()}`;
  });
  
  $('#time-holder, #time-holder2').on('focus', e => lastFocusEl = e.target);
});

<input type="text" value="" id="time-holder">
<input type="text" value="" id="time-holder2">
<input type="text" value="" id="result">

<input type="button" value="time" name="timer" id="time">
