DateTimeOffsetToFirebirdZonedTimeResolver

A class used to resolve a DateTimeOffset into the FbZonedTime value that is written into a Firebird TIME WITH TIME ZONE column.

This IResolver<DateTimeOffset, object> implementation converts a DateTimeOffset into the FbZonedTime (boxed) that the FirebirdSql.Data.FirebirdClient driver writes into a TIME WITH TIME ZONE column. The value holds the UTC time of day, and the offset as the name of a fixed-offset Etc/GMT time zone, resolved by the TimeSpanToFirebirdTimeZoneNameResolver. It is used by the FirebirdZonedTimeToDateTimeOffsetPropertyHandler and the FirebirdZonedTimeToNullableDateTimeOffsetPropertyHandler when writing the entity property back to the database.

The date part of the DateTimeOffset is not written, as a TIME WITH TIME ZONE value has none. The counterpart of this class is the FirebirdZonedValueToDateTimeOffsetResolver, which converts the value read from the column back into a DateTimeOffset. For a TIMESTAMP WITH TIME ZONE column, use the DateTimeOffsetToFirebirdZonedDateTimeResolver.

Usability

var resolver = new DateTimeOffsetToFirebirdZonedTimeResolver();
var value = resolver.Resolve(new DateTimeOffset(2026, 9, 21, 10, 30, 0, TimeSpan.FromHours(3)));
// FbZonedTime, 07:30:00 UTC in the "Etc/GMT-3" time zone (boxed)
