mohon bantuannya, saya buat modal edit dengan bootstrap... tp kenapa ketika coba input/tekan pada form modal, input bagian tgl otomatis berubah jd tanggal hari ini.. bagian table:

     <div class="panel panel-default">
  <div class="panel-body">
        <div class="table-responsive" >
                <table class="table table-bordered table-hover table-striped" id="datatables">
                    <thead>
                        <tr>
                            <th>No.</th>
                            <th>kode produk</th>
                            <th>nama produk</th>
                            <th>tanggal reject</th>
                            <th>Jumlah Resize</th>
                            <th>Jumlah HWG</th>
                            <th>Total Reject</th>
                            <th>tonase</th>
                            <th>Opsi</th>
