Struct OffsetDateTime

A local date and time in a particular calendar system, combined with an offset from UTC. This is broadly similar to DateTimeOffset in the BCL.

Syntax
[TypeConverter(typeof(OffsetDateTimeTypeConverter))]
public readonly struct OffsetDateTime : IEquatable<OffsetDateTime>, IFormattable, IXmlSerializable, IAdditionOperators<OffsetDateTime, Duration, OffsetDateTime>, ISubtractionOperators<OffsetDateTime, Duration, OffsetDateTime>, IEqualityOperators<OffsetDateTime, OffsetDateTime, bool>
Remarks

Equality is defined in a component-wise fashion: two values are the same if they represent equal date/time values (including being in the same calendar) and equal offsets from UTC. Ordering between offset date/time values has no natural definition; see OffsetDateTime.Comparer for built-in comparers.

A value of this type unambiguously represents both a local time and an instant on the timeline, but does not have a well-defined time zone. This means you cannot reliably know what the local time would be five minutes later, for example. While this doesn't sound terribly useful, it's very common in text representations.

The default value of this type is 0001-01-01T00:00:00Z (midnight on January 1st, 1 C.E. with a UTC offset of 0) in the ISO calendar.

Remarks

If the date and time is not on a tick boundary (the unit of granularity of DateTime) the value will be truncated towards the start of time.

If the offset has a non-zero second component, this is truncated as DateTimeOffset has an offset granularity of minutes.

DateTimeOffset uses the Gregorian calendar by definition, so the value is implicitly converted to the Gregorian calendar first. The result will be the same instant in time (potentially truncated as described above), but the values returned by the Year/Month/Day properties of the DateTimeOffset may not match the Year/Month/Day properties of this value.
