# QTimeZone::OffsetData Struct

struct QTimeZone::OffsetData

## Detailed Description

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

This provides the time zone offsets and abbreviation to use at a given 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.
