If you must parse a custom format without allocation, you typically have to convert to a Span<char> :

This enforces standard ISO 8601/RFC 3339 compliance. This is the recommended setting for inter-system communication to ensure data integrity. utf8jsonreader datetimeoffset rfc 3339

DateTimeOffset is a .NET struct that represents a date and time value with an offset from Coordinated Universal Time (UTC). It's commonly used to work with dates and times that have an explicit offset from UTC.

string propertyName = reader.GetString(); reader.Read(); // Move to the value return customDto; If you must parse a custom

In this scenario, you must retrieve the raw string and parse it manually using DateTimeOffset.Parse or DateTimeOffset.TryParseExact .

// Access the raw UTF-8 bytes ReadOnlySpan<byte> source = reader.ValueSpan; It's commonly used to work with dates and

| Format | Description | Example | | :--- | :--- | :--- | | | 'Z' suffix indicates Zulu time (UTC). | 2023-10-27T14:30:00Z | | Offset | Specific offset from UTC. | 2023-10-27T14:30:00+02:00 | | Fractional Seconds | Optional microseconds. | 2023-10-27T14:30:00.123Z | | Large Offset | Offset can be HH:MM or sometimes HHMM depending on strictness. | 2023-10-27T14:30:00-0500 (ISO strict usually prefers HH:MM ) |

When debugging why Utf8JsonReader refuses to parse a date, refer to these valid RFC 3339 patterns.
