| Example | Meaning | |----------------------------------|-----------------------| | 2023-10-05T14:30:00Z | UTC | | 2023-10-05T14:30:00+02:00 | UTC+2 | | 2023-10-05T14:30:00.123-05:00 | UTC-5 with fraction |

if (DateTimeOffset.TryParseExact(s, rfc3339Pattern, CultureInfo.InvariantCulture, DateTimeStyles.RoundtripKind, out DateTimeOffset result))

If you need UTC normalization:

throw new JsonException("Invalid RFC 3339 DateTimeOffset string.");

throw new JsonException("Invalid RFC 3339 format"); utf8jsonreader datetimeoffset parsing rfc 3339

if (reader.TokenType == JsonTokenType.PropertyName && reader.GetString() == "created")
