Qt qdatetime

This function was introduced in Qt 5.8. QDateTime:: ~QDateTime Destroys the datetime. QDateTime QDateTime:: addDays (qint64 ndays) const. Returns a QDateTime object containing a datetime ndays days later than the datetime of this object (or earlier if ndays is negative). If the timeSpec() is Qt::LocalTime and the resulting date and time fall in the Standard Time to Daylight-Saving Time. QString QDateTime:: toString (Qt::DateFormat format = Qt::TextDate) const. This is an overloaded function. Returns the datetime as a string in the format given. If the format is Qt::TextDate, the string is formatted in the default way. QDate::shortDayName(), QDate::shortMonthName(), and QTime::toString() are used to generate the string, so the day and month names will be localized names. An.

See also addDays(), secsTo(), and msecsTo(). [static] QDateTime QDateTime:: fromCFDate (CFDateRef date) Constructs a new QDateTime containing a copy of the CFDate date.. This function was introduced in Qt 5.5. See also toCFDate(). [static] QDateTime QDateTime:: fromMSecsSinceEpoch (qint64 msecs) Returns a datetime whose date and time are the number of milliseconds, msecs, that have passed. QDateTime takes into account transitions between Standard Time and Daylight-Saving Time. For example, if the transition is at 2am and the clock goes forward to 3am, then there is a missing hour from 02:00:00 to 02:59:59.999 which QDateTime considers to be invalid. Any date arithmetic performed will take this missing hour into account and return a valid result [static] QDateTime QDateTime :: fromSecsSinceEpoch ( qint64, Qt :: TimeSpec spec = Qt :: LocalTime, int offsetSeconds = 0) Gibt eine Datums- / Uhrzeitangabe zurück, deren Datum und Uhrzeit der Anzahl der Sekunden entspricht, die seit dem 01.01.1970, 00: 00: 00.000, Koordinierte Weltzeit ( Qt :: UTC ) vergangen sind und in die angegebene Spezifikation konvertiert wurden

  1. possible duplicate of Qt and QDateTime comparing - Pavel Strakhov Jul 20 '15 at 23:08. add a comment | 1 Answer Active Oldest Votes. 0. The problem is that the objects are compared in different formats. Replace dd.MM.yy HH: mm to dd.MM.yyyy HH: mm and will get you Happiness. it turns out that Qt compares 1915 and 2015. QDateTime now = QDateTime::currentDateTime(); QDateTime nearest.
  2. PySide2.QtCore.QDateTime.toString ([f=Qt.TextDate]) ¶ Parameters. f - DateFormat. Return type. unicode. This is an overloaded function. Returns the datetime as a string in the format given.. If the format is TextDate, the string is formatted in the default way. shortDayName(), shortMonthName(), and toString() are used to generate the string, so the day and month names will be localized.
  3. QTimeSpan was meant to go into Qt 4.8, but did not make it unfortunately. Because the time/date stuff is undergoing a rewrite for Qt 5, QTimeSpan will also need to be redone
  4. void QDateTime:: setTimeSpec ( Qt::TimeSpec spec) Sets the time specification used in this datetime to spec. See also timeSpec(), setDate(), setTime(), and Qt::TimeSpec. void QDateTime:: setTime_t ( uint seconds) Sets the date and time given the number of seconds that have passed since 1970-01-01T00:00:00, Coordinated Universal Time
  5. Vielleicht gibt sich das Qt-Creator-Problem dann. @topic: Folgender exemplarischer Code generiert mir problemlos den Zeitunterschied in Sekunden, nur der addSecs-Weg zurück zu QDateTime funktioniert nicht richtig. Scheinbar muss das Datum schon valide sein, bevor addSecs aufgerufen wird - was ja eigentlich auch logisch ist

Qt5 has QDate, QTime, and QDateTime classes to work with date and time. The QDate is a class for working with a calendar date in the Gregorian calendar. It has methods for determining the date, comparing, or manipulating dates. The QTime class works with a clock time. It provides methods for comparing time, determining the time and various other time manipulating methods. The QDateTime is a. In one of my Qt apps I show a formated date and time string in a label, updated every second. datetimelabel->setText(QDateTime::currentDateTimeUtc().toString(yyyy-MM-dd hh:mm:ss t)+\n+QDateTime::currentDateTime().toString(yyyy-MM-dd hh:mm:ss t)); When I run this app on my linux box (Qt5.5, clang) the date and time is displayed a \fn QDateTime QDate::startOfDay(Qt::TimeSpec spec, int offsetSeconds) const: 684 \fn QDateTime QDate::startOfDay(const QTimeZone &zone) const: 685: 686: Returns the start-moment of the day.

PyQt5 date and time chapter of the PyQt5 tutorial shows how to work with date and time. The example use QDate, QTime, and QDateTime classes Detailed Description. The QDateTimeAxis class adds dates and times to a chart's axis.. QDateTimeAxis can be set up to show an axis line with tick marks, grid lines, and shades. The labels can be configured by setting an appropriate DateTime format. QDateTimeAxis works correctly with dates from 4714 BCE to 287396 CE.

Ofrezco mis servicios como desarrollador de software. Hago software a la necesidad del cliente. Contacto: carlosduarte.1@hotmail.co The PySide.QtCore.QDateTime class provides date and time functions. A PySide.QtCore.QDateTime object contains a calendar date and a clock time (a datetime). It is a combination of the PySide.QtCore.QDate and PySide.QtCore.QTime classes. It can read the current datetime from the system clock The QDateTimeEdit class provides a widget for editing dates and times. QDateTimeEdit allows the user to edit dates by using the keyboard or the arrow keys to increase and decrease date and time values. The arrow keys can be used to move from section to section within the QDateTimeEdit box You probably did use the Qt 5.12 api, where NewQVariant21 was wanting an QDate object. And now in the newer 5.13 api, the NewQVariant21 function wants an QDateTime object instead. Better use NewQVariant1() to work around these kind of issues in the future. Also to get an QDateTime out of an QVariant you can use the .ToDateTime() function QDateTime QDateTime::fromString (const QString & s, Qt::DateFormat f = Qt::TextDate) [static] Returns the QDateTime represented by the string s, using the format f, or an invalid datetime if this is not possible. Note for Qt::TextDate: It is recommended that you use the English short month names (e.g. Jan). Although localized month names can.

QDateTime::toString( Qt::ISODate lacks prefixed 0's on years below 1000. The iso8601 standard dictates that this should be the case. Additionally: If the date is in UTC, A Z should be postixed, otherwise an offset for the timezone should be postfixed. Additionally: If the date is before 1/1/1 00:00:00 UTC, the method should throw instead of returning an empty string, IMO. Test example for. Returns a QDateTime object containing a datetime ndays days later than the datetime of this object (or earlier if ndays is negative).. If the timeSpec() is Qt::LocalTime and the resulting date and time fall in the Standard Time to Daylight-Saving Time transition hour then the result will be adjusted accordingly, i.e. if the transition is at 2am and the clock goes forward to 3am and the result.

Later I have to convert this date in to foramt yyyy-MM-dd HH:mm:ss, so as a first step I have convert the string in to QDateTime.

QDateTimeParser - Takes an input string, date/time format, and locale and returns a QDateTime. Existing private class to be modified. QDateTimeFormatter - Takes a QDateTime, date/time format and locale and returns a QString. New private class based on the QLocale formatter. The QDateTime formatter is to be deleted However there is often a need for time durations such 52 hours or 52:00 which QTime is unable to represent or format. Either QTime should be extended to allow for a duration mode or a QDuration/QTimeSpan class created. Basically a period of x milliseconds, but able to be relative to a start date, and having various maths and formatting functions QDate from/to JS Date has unexpected results, so use QDateTime to have a timezone assigned to prevent conversions. That way the date values are consistent. The behaviour got changed with Qt 5.11 (see the linked bug report) which lead to plasma showing the wrong dates in the calendar. BUG: 394423. Test Plan. Tested with and without this patch on Qt 5.10.1 and 5.11.0. Now the correct date is.
