Time convertion

[rajeshs]

Hi,

please any one give some way to convert time from Local to UTC and UTC to Local in Qt.

See QDateTime::setTimeSpec().

actually i tried with setTimeSpec() function, but it is not conveting time from UTC to LocalTime.

setTimeSpec() doesn't do the conversion, it only tells Qt that the date is in UTC. You also need to call toLocalTime(), toUTC() or toTimeSpec().

QDateTime d( QDate( 2008, 6, 5 ), QTime( 12, 0 ) );
d.setTimeSpec( Qt::UTC );
qDebug() << d << d.toLocalTime();

QDateTime d( QDate( 2008, 6, 5 ), QTime( 12, 0 ) );
d.setTimeSpec( Qt::UTC );
qDebug() << d << d.toLocalTime();

or

QDateTime d( QDate( 2008, 6, 5 ), QTime( 12, 0 ), QT::UTC );
qDebug() << d << d.toLocalTime();

QDateTime d( QDate( 2008, 6, 5 ), QTime( 12, 0 ), QT::UTC );
qDebug() << d << d.toLocalTime();
