Show date & time from database in html input field

I wanted to show dates from my database in my HTML input field. For example id one has "2023-01-13 17:30:00", but when I display it on my input field it just show "Jan." I wanted it to display exactly as "2023-01-13 17:30:00". You might be confused why there is a submit button but has readonly input fields, it’s for a condition where if the user is a not the admin, they can’t edit the records.

HTML file

<div class="card-body">
    <div class="form-group">
        <label >Title：</label>
            <input type="text" name="title" value={{query.title}} readonly>
    </div>
    <div class="form-group">
        <label>Description：</label>
            <input type="text" name="description" value={{query.description}} readonly>
    </div>
    <div class="form-group">
        <label>Start time：</label>
            <input type="text" name="start_time" value={{query.start_time}} readonly>
    </div>
    <div class="form-group">
        <label>End time：</label>
            <input type="text" name="end_time" value={{query.end_time}} readonly>
    </div>
    <div align="center" >
        <button type="submit" class="btn btn-primary">Submit</button>
        <button type="reset" class="btn btn-primary">Refresh</button>
    </div>
</div>
