Detailed Description

The time zone offset data for a given moment in time.

This provides the time zone offsets and abbreviation to use at that moment in time. When a function returns this type, it may use an invalid datetime to indicate that the query it is answering has no valid answer, so check atUtc.isValid() before using the results.

• OffsetData::atUtc The datetime of the offset data in UTC time.

• OffsetData::offsetFromUtc The total offset from UTC in effect at the datetime.

• OffsetData::standardTimeOffset The standard time offset component of the total offset.

• OffsetData::daylightTimeOffset The DST offset component of the total offset.

• OffsetData::abbreviation The abbreviation in effect at the datetime.

For example, for time zone "Europe/Berlin" the OffsetDate in standard and DST might be:

• atUtc = QDateTime(QDate(2013, 1, 1), QTime(0, 0), QTimeZone::UTC)

• offsetFromUtc = 3600

• standardTimeOffset = 3600

• daylightTimeOffset = 0

• abbreviation = "CET"

• atUtc = QDateTime(QDate(2013, 6, 1), QTime(0, 0), QTimeZone::UTC)

• offsetFromUtc = 7200

• standardTimeOffset = 3600

• daylightTimeOffset = 3600

• abbreviation = "CEST"

This type is only available when feature timezone is enabled.
