QDateTime Class - Q

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. return QDateTime (); 840: case Qt:: UTC: 841: case Qt:: OffsetFromUTC: 842: return QDateTime (*this, QTime (23, 59, 59, 999), spec, offsetSeconds); 843: 844: case Qt:: LocalTime: 845: if (offsetSeconds) 846: qWarning(Ignoring offset (%d seconds) passed with Qt::LocalTime, offsetSeconds); 847: break; 848} 849: QDateTime when(*this, QTime (23, 59, 59, 999), spec); 850: if (!when.isValid()) 85

QDateTime dteNow = QDateTime::currentDateTime(); if(dteNow.isValid()) { qDebug(The date is valid: %s\n, dteNow.toString()); } else { qDebug(The current date returned is invalid\n); } If this prints that the date is invalid in the Application Output window (or console, if you're running from there), clean the project and rebuild [static] QDateTime QDateTime:: fromTime_t (uint seconds) This function is obsolete. It is provided to keep old source code working. We strongly advise against using it in new code. Returns a datetime whose date and time are the number of seconds that have passed since 1970-01-01T00:00:00, Coordinated Universal Time and converted to Qt::LocalTime

  5. QDateTimeAxis works correctly with dates from 4714 BCE to 287396 CE. For other limitiations related to QDateTime, see QDateTime documentation. Note: QDateTimeAxis is disabled on platforms that define qreal as float. QDateTimeAxis can be used with any QXYSeries. To add a data point to the series, QDateTime::toMSecsSinceEpoch() is used

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.

Qt4 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 Returns the UTC offset in seconds. If the PySide.QtCore.QDateTime.timeSpec() isn't Qt.OffsetFromUTC, 0 is returned. However, since 0 is a valid UTC offset the return value of this function cannot be used to determine whether a PySide.QtCore.QDateTime.utcOffset() is used or is valid, PySide.QtCore.QDateTime.timeSpec() must be checked Gets system clock and append it to stuff. Stuff like the user name of my server/client chat room!www.oldtigersweb.comRecent college grad in NY with B.S. in C.. Since Qt 4.7, millisecond accuracy can be obtained from QDateTime by using QDateTime::fromMSecsSinceEpoch()/1000.0. The static methods dateTimeToKey and keyToDateTime conveniently perform this conversion achieving a precision of one millisecond on all Qt versions Member Function Documentation [static] QDateTime QDateTime:: fromTime_t (uint seconds) Returns a datetime whose date and time are the number of seconds that have passed since 1970-01-01T00:00:00, Coordinated Universal Time and converted to Qt::LocalTime.On systems that do not support time zones, the time will be set as if local time were Qt::UTC.. Note: This function is deprecated

QDateTime QDateTime::toTimeSpec ( Qt::TimeSpec specification) const. Returns a copy of this datetime configured to use the given time specification. See also timeSpec(), toUTC(), and toLocalTime(). uint QDateTime::toTime_t const. Returns the datetime as the number of seconds that have passed since 1970-01-01T00:00:00, Coordinated Universal Time . On systems that do not support time zones, this. QDateTime can store datetimes as \l{Qt::LocalTime}{local time} or: as \l{Qt::UTC}{UTC}. QDateTime::currentDateTime() returns a: QDateTime expressed as local time; use toUTC() to convert it to: UTC. You can also use timeSpec() to find out if a QDateTime: object stores a UTC time or a local time. Operations such as : addSecs() and secsTo() are aware of daylight saving time (DST). \note QDateTime.

QDateTime binding problem in QSqlQuery+QMYSQL on Qt4 vs

  1. The QDateTime class provides date and time functions. A QDateTime object contains a calendar date and a clock time (a datetime). It is a combination of the QDate and QTime classes. It can read the current datetime from the system clock. It provides functions for comparing datetimes and for manipulating a datetime by adding a number of seconds or days. A QDateTime object is typically created.
  2. QDateTime Conversion. Tag: qt,qdatetime. I need to convert the String variable to QDateTime format. my code looks . QString date =Thu Jun 18 2015; QDateTime tmp = QDateTime::fromString(date,ddd MMM dd yyyy HH:mm:ss); But the result is Thu Jan 1 00:00:00 1970. 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.
  3. \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. Usually, this shall be midnight at the: 687: start of the day: however, if a time-zone transition causes the given date: 688: to skip over that midnight (e.g. a DST spring-forward skipping from the end.
  4. What is the best way to construct this QDateTime object with the specified timezone and later construct an insert statement to be executed by the QSqlQuery? I find the topic of timezones and offsets and stuff pretty complicated and can't get my head around what information regarding the timezone is being saved by QDateTime. Maybe there's a recommended way for doing this. Any help is highly.

Unlike QDateTime, QTime knows nothing about time zones or daylight savings time (DST).
