    Description

      As stated on https://doc.qt.io/qt-5/qtimezone.html#NameType-enum - shortName should  return the short form of the time zone name, usually an abbreviation, e.g. "CET".

      I've tested this on both Mac & Win:

      • on OSX it returns "GMT+offset"
      • on Windows it returns the LongName as a timeZone, never its shortName abbreviation. e.g. "Central European Time"

       

      e.g. 

       

      QDateTime currentDateTime = QDateTime::currentDateTime(); 

qDebug() << currentDateTime.timeZone().displayName(currentDateTime,QTimeZone::DefaultName) << 
currentDateTime.timeZone().displayName(currentDateTime,QTimeZone::LongName) 
<< currentDateTime.timeZone().displayName(currentDateTime,QTimeZone::ShortName) << currentDateTime.timeZone().displayName(currentDateTime,QTimeZone::OffsetName);

       

       on MacOs returns:

      "Central European Summer Time" 
"Central European Summer Time" 
"GMT+2" 
"UTC+02:00"

      & on Windows the same code returns:

      "Central Europe Daylight Time" 
"Central Europe Daylight Time" 
"Central Europe Daylight Time" 
"UTC+02:00"
