服务时区设置为+8，在命令行行下显示正常，XOOPS中设置服务器所在时区为+0800，可article输出的feed时时间却怎么也不对，导致outlookRSS订阅中显示的文章时间也不对均为GMT+1600时区，哪有这样的时区哦，时区范围GMT-1200～GMT+1200。
修改方法如下：
1、修改htdocs\modules\article\class\feedcreator.class.php文件中739行附近FeedDate类的构造函数FeedDate如下：
1: function FeedDate($dateString="") {
2: $tzOffset = 0;
3: if ($dateString=="") $dateString = date("r");
4:
5: //if (is_integer($dateString)) {
6: if (is_numeric($dateString)) {
7: $this->unix = $dateString;
8: return;
9: }
10: //Hack By XuYong 调整日期格式
11: if (preg_match("~(?:(?:Mon|Tue|Wed|Thu|Fri|Sat|Sun),\\s+)?(\\d{1,2})\\s+([a-zA-Z]{3})\\s+(\\d{4})\\s+(\\d{2}):(\\d{2}):(\\d{2})\\s+(.*)~",$dateString,$matches)) {
12: $months = Array("Jan"=>1,"Feb"=>2,"Mar"=>3,"Apr"=>4,"May"=>5,"Jun"=>6,"Jul"=>7,"Aug"=>8,"Sep"=>9,"Oct"=>10,"Nov"=>11,"Dec"=>12);
13: $this->unix = gmmktime($matches[4],$matches[5],$matches[6],$months[$matches[2]],$matches[1],$matches[3]);
14: if (substr($matches[7],0,1)=='+' OR substr($matches[7],0,1)=='-') {
15: $tzOffset = (substr($matches[7],0,3) * 60 + substr($matches[7],-2)) * 60;
16: } else {
17: if (strlen($matches[7])==1) {
18: $oneHour = 3600;
19: $ord = ord($matches[7]);
20: if ($ord < ord("M")) {
21: $tzOffset = (ord("A") - $ord - 1) * $oneHour;
22: } elseif ($ord >= ord("M") AND $matches[7]!="Z") {
23: $tzOffset = ($ord - ord("M")) * $oneHour;
24: } elseif ($matches[7]=="Z") {
25: $tzOffset = 0;
26: }
27: }
28: switch ($matches[7]) {
29: case "UT":
30: case "GMT": $tzOffset = 0;
31: }
32: }
33:
34: $tzOffset += date("Z",0);
35: $this->unix += $tzOffset;
36:
37: if (TIME_ZONE!="")
38: {
39: $server_TZ = abs(intval($GLOBALS['xoopsConfig']['server_TZ'] * 3600.0));
40: $this->unix += ($server_TZ - date("Z", 0)) % 43200;
41: }
42:
43: return;
44: }
45: if (preg_match("~(\\d{4})-(\\d{2})-(\\d{2})T(\\d{2}):(\\d{2}):(\\d{2})(.*)~",$dateString,$matches)) {
46: $this->unix = gmmktime($matches[4],$matches[5],$matches[6],$matches[2],$matches[3],$matches[1]);
47: if (substr($matches[7],0,1)=='+' OR substr($matches[7],0,1)=='-') {
48: $tzOffset = (substr($matches[7],0,3) * 60 + substr($matches[7],-2)) * 60;
49: } else {
50: if ($matches[7]=="Z") {
51: $tzOffset = 0;
52: }
53: }
54: $tzOffset += date("Z",0);
55: $this->unix += $tzOffset;
56:
57: if (TIME_ZONE!="")
58: {
59: $server_TZ = abs(intval($GLOBALS['xoopsConfig']['server_TZ'] * 3600.0));
60: $this->unix += ($server_TZ - date("Z", 0)) % 43200;
61: }
62: return;
63: }
64: $this->unix = 0;
65: }
2、修改htdocs\modules\article\class\xml.php文件58行，
原来为：
$TIME_ZONE = $prefix.date(“H:i”, $server_TZ);
修改为：
$TIME_ZONE = $prefix.date(“H:i”, ($server_TZ – date(“Z”, 0)) % 43200); //Hack By XuYong 调整时区显示，防止出现+1600时区
