@Austin27 please refer this:
1. Server Script

(function() {
    // Get sys_id from the widget parameter
    data.sys_id = $sp.getParameter("sys_id");

    // Query the widget table for the given sys_id
    var widgetGr = new GlideRecord("sp_widget");
    widgetGr.addQuery("sys_id", data.sys_id);
    widgetGr.query();

    if (widgetGr.next()) {
        // Retrieve the sys_updated_on field value as a GlideDateTime object
        var modifiedTime = widgetGr.getValue("sys_updated_on");

        // Convert the GlideDateTime to a formatted string
        var gdt = new GlideDateTime(modifiedTime);
        data.modifiedTime = gdt.getDate().getByFormat("MMM dd, yyyy HH:mm:ss");
    }
})();

2. Client Script

function($scope, $sce) {
    var c = this;

    // Watch for changes in the data object and trust the HTML content
    $scope.$watch('c.data.modifiedTime', function(newValue) {
        if (newValue) {
            c.modifiedTime_html = $sce.trustAsHtml(newValue);
        }
    });
}

<p ng-bind-html="c.modifiedTime_html"></p>
