Pangea Я устал, когда читал ваше сообщение, я хотел опубликовать решение и прочитал его обратно, и теперь я понимаю, что мог бы сделать это намного проще, попробовав нулевой возврат или попробовав другой шаблон..
В любом случае это был трудный путь решения:
String[] days = {
"Mon", "Tue", "Wed", "Thu", "Fri", "Sat", "Sun"
};
String[] months = {
"Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"
};
String[] years = {
"2004", "2005", "2006", "2007", "2008", "2009", "2010", "2011"
};
// ORDER IS VERRY IMPORTANT!! ( MEST must be before EST for example)
String[] timesZones = {
"BST", "CET", "CEST", "CST", "CDT", "EDT", "GMT+00:00", "GMT", "IST", "MEST", "EST", "MET", "MDT", "PST", "PDT", "SAST", "UTC", "UT", "W. Europe Standard Time", "West-Europa (zomertijd)"
};

String month = "";
String day = "";
int hours = 0;
int minutes = 0;
int seconds = 0;
// is it valid?
date = trim(date);
if (date.equals("")) {
return null;
}
// first delete the comma that comes mostly after the day
date = date.replaceAll(",", "");
// remove the day
for (int i = 0; i < days.length; i++) {
if (date.contains(days[i])) {
date = date.replace(days[i], "");
break;
}
}
// if(date.contains("23:27:17")) println(date);
