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 This function was introduced in Qt 5.2. See also toTime_t() and setTime_t(). [static] QDateTime QDateTime:: fromTime_t (uint seconds, const QTimeZone &timeZone) This function is obsolete. It is provided to keep old source code working. We strongly advise against using it in new code
QDate, QTime, QDateTime PyQt5 has QDate, QDateTime, QTime 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 QDateTime::toString() QTime::toString(). See also QDate::fromString(), QTime::fromString(), and QDate::toString(). [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 ().On systems that do not support time zones, the time will be set as if local time were. I create a valid QDatetime, make a string out of it (that is correct) and try to turn it into a QDatetime again (using the same time_format-string). But suddenly, the string can't be parsed.

QDateTime wasn't really written to be extensible, I am afraid, so subclassing QDateTime doesn't sound like a promising approach. You may have to write your own TickDateTime class. Please also notice that not all platforms support such granularity (one reason that QDateTime is based on milliseconds is that that is a granularity that all platforms supported by Qt these days support themselves.

QDateTime. This page details the discussions about QDateTime in the Date/Time and Localisation sessions. This page was written by John Layt from KDE (jlayt@kde.org)..

Changed in version 3.5: Before Python 3.5, a time object was considered to be false if it represented midnight in UTC. This behavior was considered obscure and error-prone and has been removed in Python 3.5. See bpo-13936 for full details qdatetime.h. This is the verbatim text of the qdatetime.h include file.

This property holds the minimum datetime of the date time edit. When setting this property the maximumDateTime() is adjusted if necessary to ensure that the range remains valid. If the datetime is not a valid QDateTime object, this function does nothing. The default minimumDateTime can be restored with.

In 5.1, calling toLocalTime on an invalid QDateTime returns an invalid QDateTime. In 5.2 it returns a 'valid' QDateTime. Probably QDateTime::toTimeSpec needs to add a check for whether the current QDateTime is valid or not Adjusting the v-model value on a qDatetime via the :after button handler sets the input, but not the popup value.

The value returned by the conversion is a DateTime whose Kind property always returns Local.Consequently, a valid result is returned even if ToLocalTime is applied repeatedly to the same DateTime.. Notes to Callers. You can use the ToLocalTime() method to restore a local date and time value that was converted to UTC by the ToUniversalTime() or FromFileTimeUtc(Int64) method You can instantiate another QDateTime object to the same time but having the TimeSpec as Qt::LocalTime or Qt::TimeZone. You can e.g. convert to local time with QDateTime::toLocalTime or to either Qt::LocalTime or Qt::TimeZone with QDateTime::fromSecsSinceEpoch which accepts offset seconds for time zone.
