Howto
Download the above script, rename it as spip_localtime_en.js, upload it to the root directory of your server and write the following code in the HEAD section of your templates:
<script language="JavaScript" type="text/javascript" src="spip_localtime_en.js"></script>Then, paste this code in yoyr mes_fonctions.php3 file:
function localtime_js($date, $format = "Y-m-d H:i:s") {
return "<script language=\"JavaScript\" type=\"text/javascript\">s_lt(".strtotime($date).", '".str_replace('\\', '\\\\', $format)."');</script><noscript>".date($format, strtotime($date))." UTC</noscript>";
}Eventually, place this code in your templates:
[(#DATE|localtime_js{'y-m-d H:i'})]This date format between brackets is quite the same as function date in PHP. The supported codes are: d, F, G, H, i, j, l, m, n, s, Y and y. It also supports anti-slashes to escape characters.
Limits
Server timezone needs to be UTC (or the script needs some modifications).
If the browser doesn’t support JavaScript, date and time are displayed in UTC.
