@ambershark Thanks
it work for me
QDateTime now = QDateTime::currentDateTime();
QString timestamp = now.toString(QLatin1String("yyyyMMdd-hhmm"));
QString filename = QString::fromLatin1("/path/%1.csv").arg(timestamp);
QFile file(filename);
if(!file.open(QIODevice::WriteOnly | QIODevice::Text))
{
// write data
}
file.close();
