Note: All functions in this class are reentrant. A QDateTime object encodes a calendar date and a clock time a "datetime" in accordance with a time representation. It combines features 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, days, months, or years. Each of these time representations can be encapsulated in a suitable instance of the QTimeZone class.

Kristin Forbes. Roula Khalaf, Editor of the FT, selects her favourite stories in this weekly newsletter. The Federal Reserve will discuss later this month whether to adjust its quantitative tightening programme that is unwinding the huge asset purchase operations it carried out to support the US economy and markets. We finally have some international evidence on how QT works. A new study by myself with Wenxin Du and Matthew Luzzetti uses these experiences to assess the impact of announcing and implementing QT — as well as the advantages and disadvantages of different strategies. You are seeing a snapshot of an interactive graphic. This is most likely due to being offline or JavaScript being disabled in your browser. QT programmes have, so far, been working as central banks intended. QT has worked in the opposite direction to quantitative easing, but the effects are much, much more muted. More specifically, announcing the start of QT causes a modest increase in yields of about 0. Other effects are even harder to pin down — albeit generally pointing in the direction of tighter financial conditions. These muted effects continue when central banks begin implementing the programmes and some even selling their bonds outright. There has been minimal impact on bond pricing and liquidity, to date.

For example, the following string could have meantbut the m will grab two digits, resulting in an invalid time:. Returns true if lhs is qt times from rhs ; otherwise returns false.

The QElapsedTimer class provides a fast way to calculate elapsed times. Note: All functions in this class are reentrant. The QElapsedTimer class is usually used to quickly calculate how much time has elapsed between two events. Its API is similar to that of QTime , so code that was using that can be ported quickly to the new class. This means it's not possible to convert QElapsedTimer objects to a human-readable time. The typical use-case for the class is to determine how much time was spent in a slow operation.

The maximum slope intercept method defines the end of the T wave as the intercept between the isoelectric line with the tangent drawn through the maximum down slope of the T wave left. When notched T waves are present right , the QT interval is measured from the beginning of the QRS complex to the intersection point between the isoelectric line and the tangent drawn from the maximum down slope of the second notch. There are multiple formulas used to estimate QTc. It is not clear which formula is the most useful:. In the context of acute poisoning with QT-prolonging agents, the risk of TdP is better described by the absolute rather than corrected QT. ECG Library Basics.

The Queensland Times is the oldest surviving provincial paper in Queensland. Founded on 4 July as the Ipswich Herald , it has continued ever since. It was not, however, the first newspaper in Ipswich. That honour belongs to the North Australian , founded in and having on its staff two men who were to play a major part in the establishment of other Queensland newspapers, Hugh Parkinson, the foremen printer, and Arthur Sidney Lyon , the editor. The publishing office of this paper was moved to Brisbane in One of the main aims of the Ipswich Herald was to promote Ipswich's claims to be capital city of the Moreton bay colony as separation from New South Wales loomed. They changed its name to The Queensland Times and said it "would undertake to speak as from the centre of authority, the capital, and would oppose centralization in Brisbane. The greatest success story connected with the paper was that of a young lad, William Kippen, who rose from the position of paper seller in to become chairman of directors in Between the s and the s the bi-weekly Queensland Times faced competition from other newspapers, but outlasted them all.

Thank you all for answers and hints. Because QTime measures time within a day and there are seconds in a day, the result is always between and ms. The exact range of supported values varies depending on the time representation used. Also unlike QTime , QElapsedTimer is immune to changes in the timezone settings, such as daylight-saving periods. Returns true if lhs is earlier than rhs ; otherwise returns false. If date is invalid, this QDateTime becomes invalid. Returns true if lhs is earlier than rhs ; otherwise returns false. The expressions that don't have leading zeroes d, M, h, m, s, z will be greedy. QDateTime likewise uses system-provided information to determine the offsets of other timezones from UTC. An invalid object can be checked with isValid. Returns true if the specified time is valid; otherwise returns false. If time is not valid, this function sets it to midnight. Modifies this datetime object by subtracting the given duration.

QT prolongation occurs when the heart muscle takes longer to contract and relax than usual. It can affect heart rhythms and lead to sudden cardiac arrest. The heart is a muscle that contracts and relaxes to pump blood around the body.

A QDateTime object encodes a calendar date and a clock time a "datetime" in accordance with a time representation. A datetime is valid if both its date and its time are valid and the time representation used gives a valid meaning to their combination. See also daysTo , addDays , addYears , and addSecs. An example of this formatting is "Wed May 20 ". Tech Show more Tech. See also start , restart , hasExpired , and invalidate. For example:. If date is valid and time is not, the time will be set to midnight. See also hour , minute , and second. Modifies this datetime object by subtracting the given duration. This means that they will use two digits or three, for z even if this puts them outside the range of accepted values and leaves too few digits for other sections.
