<!-- $$$QDateTime-description -->
<div class="descr">
<h2>Detailed Description</h2>
<p>The QDateTime class provides date and time functions.</p>
<p>A QDateTime object contains a calendar date and a clock time (a "datetime"). It is a combination of the <a href="qdate.html">QDate</a> and <a href="qtime.html">QTime</a> 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, days, months, or years.</p>
<p>A QDateTime object is typically created either by giving a date and time explicitly in the constructor, or by using the static function <a href="qdatetime.html#currentDateTime">currentDateTime</a>() that returns a QDateTime object set to the system clock's time. The date and time can be changed with <a href="qdatetime.html#setDate">setDate</a>() and <a href="qdatetime.html#setTime">setTime</a>(). A datetime can also be set using the <a href="qdatetime.html#setTime_t">setTime_t</a>() function that takes a POSIX-standard "number of seconds since 00:00:00 on January 1, 1970" value. The <a href="qdatetime.html#fromString">fromString</a>() function returns a QDateTime, given a string and a date format used to interpret the date within the string.</p>
<p>The <a href="qdatetime.html#date">date</a>() and <a href="qdatetime.html#time">time</a>() functions provide access to the date and time parts of the datetime. The same information is provided in textual format by the <a href="qdatetime.html#toString">toString</a>() function.</p>
<p>QDateTime provides a full set of operators to compare two QDateTime objects where smaller means earlier and larger means later.</p>
<p>You can increment (or decrement) a datetime by a given number of milliseconds using <a href="qdatetime.html#addMSecs">addMSecs</a>(), seconds using <a href="qdatetime.html#addSecs">addSecs</a>(), or days using <a href="qdatetime.html#addDays">addDays</a>(). Similarly you can use <a href="qdatetime.html#addMonths">addMonths</a>() and <a href="qdatetime.html#addYears">addYears</a>(). The <a href="qdatetime.html#daysTo">daysTo</a>() function returns the number of days between two datetimes, <a href="qdatetime.html#secsTo">secsTo</a>() returns the number of seconds between two datetimes, and <a href="qdatetime.html#msecsTo">msecsTo</a>() returns the number of milliseconds between two datetimes.</p>
<p>QDateTime can store datetimes as <a href="qt.html#TimeSpec-enum">local time</a> or as <a href="qt.html#TimeSpec-enum">UTC</a>. <a href="qdatetime.html#currentDateTime">QDateTime::currentDateTime</a>() returns a QDateTime expressed as local time; use <a href="qdatetime.html#toUTC">toUTC</a>() to convert it to UTC. You can also use <a href="qdatetime.html#timeSpec">timeSpec</a>() to find out if a QDateTime object stores a UTC time or a local time. Operations such as <a href="qdatetime.html#addSecs">addSecs</a>() and <a href="qdatetime.html#secsTo">secsTo</a>() are aware of daylight saving time (DST).</p>
<p><b>Note:</b> QDateTime does not account for leap seconds.</p>
<a name="use-of-gregorian-and-julian-calendars"></a>
<a name="qdatetime-g-and-j"></a><a name="use-of-gregorian-and-julian-calendars"></a>
<h4>Use of Gregorian and Julian Calendars</h4>
<p><a href="qdate.html">QDate</a> uses the Gregorian calendar in all locales, beginning on the date 15 October 1582. For dates up to and including 4 October 1582, the Julian calendar is used. This means there is a 10-day gap in the internal calendar between the 4th and the 15th of October 1582. When you use QDateTime for dates in that epoch, the day after 4 October 1582 is 15 October 1582, and the dates in the gap are invalid.</p>
<p>The Julian to Gregorian changeover date used here is the date when the Gregorian calendar was first introduced, by Pope Gregory XIII. That change was not universally accepted and some localities only executed it at a later date (if at all). QDateTime doesn't take any of these historical facts into account. If an application must support a locale-specific dating system, it must do so on its own, remembering to convert the dates using the Julian day.</p>
<a name="no-year-0"></a>
<h4>No Year 0</h4>
<p>There is no year 0. Dates in that year are considered invalid. The year -1 is the year "1 before Christ" or "1 before current era." The day before 0001-01-01 is December 31st, 1 BCE.</p>
<a name="range-of-valid-dates"></a>
<h4>Range of Valid Dates</h4>
<p>The range of valid dates is from January 2nd, 4713 BCE, to sometime in the year 11 million CE. The Julian Day returned by <a href="qdate.html#toJulianDay">QDate::toJulianDay</a>() is a number in the contiguous range from 1 to <i>overflow</i>, even across QDateTime's "date holes". It is suitable for use in applications that must convert a QDateTime to a date in another calendar system, e.g., Hebrew, Islamic or Chinese.</p>
<p>The Gregorian calendar was introduced in different places around the world on different dates. QDateTime uses <a href="qdate.html">QDate</a> to store the date, so it uses the Gregorian calendar for all locales, beginning on the date 15 October 1582. For dates up to and including 4 October 1582, QDateTime uses the Julian calendar. This means there is a 10-day gap in the QDateTime calendar between the 4th and the 15th of October 1582. When you use QDateTime for dates in that epoch, the day after 4 October 1582 is 15 October 1582, and the dates in the gap are invalid.</p>
<a name="use-of-system-timezone"></a>
<h4>Use of System Timezone</h4>
<p>QDateTime uses the system's time zone information to determine the offset of local time from UTC. If the system is not configured correctly or not up-to-date, QDateTime will give wrong results as well.</p>
<a name="daylight-savings-time-dst"></a>
<h4>Daylight Savings Time (DST)</h4>
<p>QDateTime takes into account the system's time zone information when dealing with DST. On modern Unix systems, this means it applies the correct historical DST data whenever possible. On Windows and Windows CE, where the system doesn't support historical DST data, historical accuracy is not maintained with respect to DST.</p>
<p>The range of valid dates taking DST into account is 1970-01-01 to the present, and rules are in place for handling DST correctly until 2037-12-31, but these could change. For dates falling outside that range, QDateTime makes a <i>best guess</i> using the rules for year 1970 or 2037, but we can't guarantee accuracy. This means QDateTime doesn't take into account changes in a locale's time zone before 1970, even if the system's time zone database supports that information.</p>

<p>This is an overloaded function.</p>
<p>Returns the datetime as a string in the <i>format</i> given.</p>
<p>If the <i>format</i> is <a href="qt.html#DateFormat-enum">Qt::TextDate</a>, the string is formatted in the default way. <a href="qdate.html#shortDayName">QDate::shortDayName</a>(), <a href="qdate.html#shortMonthName">QDate::shortMonthName</a>(), and <a href="qtime.html#toString">QTime::toString</a>() are used to generate the string, so the day and month names will be localized names. An example of this formatting is "Wed May 20 03:40:13 1998".</p>
<p>If the <i>format</i> is <a href="qt.html#DateFormat-enum">Qt::ISODate</a>, the string format corresponds to the ISO 8601 extended specification for representations of dates and times, taking the form YYYY-MM-DDTHH:mm:ss[Z|[+|-]HH:mm], depending on the <a href="qdatetime.html#timeSpec">timeSpec</a>() of the <a href="qdatetime.html">QDateTime</a>. If the <a href="qdatetime.html#timeSpec">timeSpec</a>() is <a href="qt.html#TimeSpec-enum">Qt::UTC</a>, Z will be appended to the string; if the <a href="qdatetime.html#timeSpec">timeSpec</a>() is <a href="qt.html#TimeSpec-enum">Qt::OffsetFromUTC</a> the offset in hours and minutes from UTC will be appended to the string.</p>
<p>If the <i>format</i> is <a href="qt.html#DateFormat-enum">Qt::SystemLocaleShortDate</a> or <a href="qt.html#DateFormat-enum">Qt::SystemLocaleLongDate</a>, the string format depends on the locale settings of the system. Identical to calling <a href="qlocale.html#system">QLocale::system</a>().toString(datetime, <a href="qlocale.html#FormatType-enum">QLocale::ShortFormat</a>) or <a href="qlocale.html#system">QLocale::system</a>().toString(datetime, <a href="qlocale.html#FormatType-enum">QLocale::LongFormat</a>).</p>
<p>If the <i>format</i> is <a href="qt.html#DateFormat-enum">Qt::DefaultLocaleShortDate</a> or <a href="qt.html#DateFormat-enum">Qt::DefaultLocaleLongDate</a>, the string format depends on the default application locale. This is the locale set with <a href="qlocale.html#setDefault">QLocale::setDefault</a>(), or the system locale if no default locale has been set. Identical to calling QLocale().toString(datetime, <a href="qlocale.html#FormatType-enum">QLocale::ShortFormat</a>) or QLocale().toString(datetime, <a href="qlocale.html#FormatType-enum">QLocale::LongFormat</a>).</p>
<p>If the datetime is invalid, an empty string will be returned.</p>
<p><b>Warning:</b> The <a href="qt.html#DateFormat-enum">Qt::ISODate</a> format is only valid for years in the range 0 to 9999. This restriction may apply to locale-aware formats as well, depending on the locale settings.</p>

<p>Returns the datetime as the number of seconds that have passed since 1970-01-01T00:00:00, Coordinated Universal Time (<a href="qt.html#TimeSpec-enum">Qt::UTC</a>).</p>
<p>On systems that do not support time zones, this function will behave as if local time were <a href="qt.html#TimeSpec-enum">Qt::UTC</a>.</p>
<p><b>Note:</b> This function returns a 32-bit unsigned integer, so it does not support dates before 1970, but it does support dates after 2038-01-19T03:14:06, which may not be valid time_t values. Be careful when passing those time_t values to system functions, which could interpret them as negative dates.</p>
<p>If the date is outside the range 1970-01-01T00:00:00 to 2106-02-07T06:28:14, this function returns -1 cast to an unsigned integer (i.e., 0xFFFFFFFF).</p>
