may be used whenever a
<a href="qtime.html">QTime</a>
is expected.</p>
<p>The QTime class provides clock time functions.</p>
<p>A QTime object contains a clock time, i.e. the number of hours,
minutes, seconds, and milliseconds since midnight. It can read the
current time from the system clock and measure a span of elapsed
time. It provides functions for comparing times and for
manipulating a time by adding a number of milliseconds.</p>
<p>QTime uses the 24-hour clock format; it has no concept of AM/PM.
Unlike <a href="qdatetime.html">QDateTime</a>, QTime knows nothing
about time zones or daylight savings time (DST).</p>
<p>A QTime object is typically created either by giving the number
of hours, minutes, seconds, and milliseconds explicitly, or by
using the static function <a href="qtime.html#currentTime">currentTime</a>(), which creates a QTime
object that contains the system's local time. Note that the
accuracy depends on the accuracy of the underlying operating
system; not all systems provide 1-millisecond accuracy.</p>
<p>The <a href="qtime.html#hour">hour</a>(), <a href="qtime.html#minute">minute</a>(), <a href="qtime.html#second">second</a>(), and <a href="qtime.html#msec">msec</a>() functions provide access to the number
of hours, minutes, seconds, and milliseconds of the time. The same
information is provided in textual format by the <a href="qtime.html#toString">toString</a>() function.</p>
<p>QTime provides a full set of operators to compare two QTime
objects. One time is considered smaller than another if it is
earlier than the other.</p>
<p>The time a given number of seconds or milliseconds later than a
given time can be found using the <a href="qtime.html#addSecs">addSecs</a>() or <a href="qtime.html#addMSecs">addMSecs</a>() functions. Correspondingly,
the number of seconds or milliseconds between two times can be
found using <a href="qtime.html#secsTo">secsTo</a>() or <a href="qtime.html#msecsTo">msecsTo</a>().</p>
<p>QTime can be used to measure a span of elapsed time using the
<a href="qtime.html#start">start</a>(), <a href="qtime.html#restart">restart</a>(), and <a href="qtime.html#elapsed">elapsed</a>() functions.</p>
<hr /><h2>Method Documentation</h2><h3 class="fn"><a name="QTime" />QTime.__init__ (<i>self</i>)</h3><p>Constructs a null time object. A null time can be a <a href="qtime.html">QTime</a>(0, 0, 0, 0) (i.e., midnight) object, except
that <a href="qtime.html#isNull">isNull</a>() returns true and
<a href="qtime.html#isValid">isValid</a>() returns false.</p>
<p><b>See also</b> <a href="qtime.html#isNull">isNull</a>() and
<a href="qtime.html#isValid">isValid</a>().</p>
<h3 class="fn"><a name="QTime-2" />QTime.__init__ (<i>self</i>, int <i>h</i>, int <i>m</i>, int <i>second</i> = 0, int <i>msec</i> = 0)</h3><p>Constructs a time with hour <i>h</i>, minute <i>m</i>, seconds
<i>s</i> and milliseconds <i>ms</i>.</p>
<p><i>h</i> must be in the range 0 to 23, <i>m</i> and <i>s</i>
must be in the range 0 to 59, and <i>ms</i> must be in the range 0
to 999.</p>

time <i>ms</i> milliseconds later than the time of this object (or
earlier if <i>ms</i> is negative).</p>
<p>Note that the time will wrap if it passes midnight. See <a href="qtime.html#addSecs">addSecs</a>() for an example.</p>
<p><b>See also</b> <a href="qtime.html#addSecs">addSecs</a>(),
<a href="qtime.html#msecsTo">msecsTo</a>(), and <a href="qdatetime.html#addMSecs">QDateTime.addMSecs</a>().</p>
<h3 class="fn"><a name="addSecs" /><a href="qtime.html">QTime</a> QTime.addSecs (<i>self</i>, int <i>secs</i>)</h3><p>Returns a <a href="qtime.html">QTime</a> object containing a
time <i>s</i> seconds later than the time of this object (or
earlier if <i>s</i> is negative).</p>
<p>Note that the time will wrap if it passes midnight.</p>

<h3 class="fn"><a name="currentTime" /><a href="qtime.html">QTime</a> QTime.currentTime ()</h3><p>Returns the current time as reported by the system clock.</p>
<p>Note that the accuracy depends on the accuracy of the underlying
operating system; not all systems provide 1-millisecond
accuracy.</p>
<h3 class="fn"><a name="elapsed" />int QTime.elapsed (<i>self</i>)</h3><p>Returns the number of milliseconds that have elapsed since the
last time <a href="qtime.html#start">start</a>() or <a href="qtime.html#restart">restart</a>() was called.</p>
<p>Note that the counter wraps to zero 24 hours after the last call
to <a href="qtime.html#start">start</a>() or restart.</p>
<p>Note that the accuracy depends on the accuracy of the underlying

<p><b>Warning:</b> If the system's clock setting has been changed
since the last time <a href="qtime.html#start">start</a>() or

is undefined. This can happen when daylight savings time is turned

time if this is not possible.</p>
<p>Note that fromString() uses a "C" locale encoded string to
convert milliseconds to a float value. If the default locale is not
"C", this may result in two conversion attempts (if the conversion
fails for the default locale). This should be considered an
implementation detail.</p>
<h3 class="fn"><a name="fromString-2" /><a href="qtime.html">QTime</a> QTime.fromString (QString <i>s</i>, QString <i>format</i>)</h3><p>Returns the <a href="qtime.html">QTime</a> represented by the

<p>If the format is not satisfied an invalid <a href="qtime.html">QTime</a> is returned. Expressions that do not expect
leading zeroes to be given (h, m, s and z) are greedy. This means
that they will use two digits even if this puts them outside the
range of accepted values and leaves too few digits for other
sections. For example, the following string could have meant
00:07:10, but the m will grab two digits, resulting in an invalid
time:</p>
<pre class="cpp">
<span class="type"><a href="qtime.html">QTime</a></span> time <span class="operator">=</span> <span class="type"><a href="qtime.html">QTime</a></span><span class="operator">.</span><a href="qtime.html#fromString">fromString</a>(<span class="string">"00:710"</span><span class="operator">,</span> <span class="string">"hh:ms"</span>); <span class="comment">// invalid</span>

milliseconds that have elapsed since the last time <a href="qtime.html#start">start</a>() or restart() was called.</p>
<p>This function is guaranteed to be atomic and is thus very handy
for repeated measurements. Call <a href="qtime.html#start">start</a>() to start the first measurement, and
restart() for each later measurement.</p>
<p>Note that the counter wraps to zero 24 hours after the last call
to <a href="qtime.html#start">start</a>() or restart().</p>
<p><b>Warning:</b> If the system's clock setting has been changed

is negative.</p>
<p>Because <a href="qtime.html">QTime</a> measures time within a

<p>If the datetime is invalid, an empty string will be returned. If

<h3 class="fn"><a name="toString-2" />QString QTime.toString (<i>self</i>, QString <i>format</i>)</h3><p>This is an overloaded function.</p>
<p>Returns the time as a string. Milliseconds are not included. The
<i>format</i> parameter determines the format of the string.</p>
<p>If <i>format</i> is <a href="qt.html#DateFormat-enum">Qt.TextDate</a>, the string format is
HH:mm:ss; e.g. 1 second before midnight would be "23:59:59".</p>
<p>If <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, which is also HH:mm:ss. (However,
contrary to ISO 8601, dates before 15 October 1582 are handled as
Julian dates, not Gregorian dates. See <a href="qdate.html#qdate-g-and-j">Use of Gregorian and Julian
Calendars</a>. This might change in a future version of Qt.)</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(time, <a href="qlocale.html#FormatType-enum">QLocale.ShortFormat</a>) or
<a href="qlocale.html#system">QLocale.system</a>().toString(time,
<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(time, <a href="qlocale.html#FormatType-enum">QLocale.ShortFormat</a>) or
QLocale().toString(time, <a href="qlocale.html#FormatType-enum">QLocale.LongFormat</a>).</p>
