How to convert from a custom date format into a UTC string using Qt.

gistfile1.cpp

QDateTime timeConvertor;
QString customDateString = "14-Nov-2010 05:27:03 +0100";

QString dateTime = customDateString.left(20).trim();
int timezoneOffset = customDateString.right(5).left(3).toInt();
timeConvertor = QDateTime::fromString(dateTime, "dd-MMM-yyyy HH:mm:ss");

// Mark this QDateTime as one with a certain offset from UTC, and set that
// offset.
timeConvertor.setTimeSpec(Qt::OffsetFromUTC);
timeConvertor.setUtcOffset(timezoneOffset * 3600);

// Convert this QDateTime to UTC.
timeConvertor = timeConvertor.toUTC();

// Store the UTC timestamp.
int timestamp = timeConvertor.toTime_t();
