RegularExpressionValidator正则失灵了

Question

<asp:TextBox ID="newsTime" runat="server" class="input"></asp:TextBox>
<asp:RequiredFieldValidator ID="RequiredFieldValidator2" runat="server" ControlToValidate="newsTime"
ErrorMessage="请输入时间">*</asp:RequiredFieldValidator>
<asp:RegularExpressionValidator ID="RegularExpressionValidator2" ControlToValidate="newsTime" runat="server" ErrorMessage="日期不符合格式" ValidationExpression="^(?ni:(?=\d)((?'year'((1[6-9])|([2-9]\d))\d\d)(?'sep'[/.-])(?'month'0?[1-9]|1[012])\2(?'day'((?<!(\2((0?[2469])|11)\2))31)|(?<!\2(0?2)\2)(29|30)|((?<=((1[6-9]|[2-9]\d)(0[48]|[2468][048]|[13579][26])|(16|[2468][048]|[3579][26])00)\2\3\2)29)|((0?[1-9])|(1\d)|(2[0-8])))(?:(?=\x20\d)\x20|$))?((?<time>((0?[1-9]|1[012])(:[0-5]\d){0,2}(\x20[AP]M))|([01]\d|2[0-3])(:[0-5]\d){1,2}))?)$"></asp:RegularExpressionValidator>点击修改后，TextBox 为空提示*
时间格式错误后不提示日期不符合格式
RequiredFieldValidator为空是提示的，RegularExpressionValidator 时间格式代码不判断
RegularExpressionValidator 以前还能用，现在怎么失灵了？？ 代码没动过，copy过来的...正则RegularExpressionV

代码复制的有问题，重新替换好了
