using System; using System.Text.Json;
reader.Read(); // move to value DateTimeOffset dto = reader.GetDateTimeOffset(); // parses RFC 3339 Console.WriteLine(dto); // 4/14/2026 12:00:00 PM +00:00
In this scenario, you must retrieve the raw string and parse it manually using DateTimeOffset.Parse or DateTimeOffset.TryParseExact . utf8jsonreader datetimeoffset rfc 3339
When working with JSON data, DateTimeOffset can be used to deserialize date and time values from JSON.
Note that the DateTimeOffset struct can also be used to serialize date and time values to JSON in RFC 3339 format. You can use the System.Text.Json namespace to serialize a DateTimeOffset instance to JSON. using System; using System
while (reader.Read())
public class Rfc3339DateTimeOffsetParser You can use the System
if (DateTimeOffset.TryParse(dateString, out DateTimeOffset dateTimeOffset))
if (propertyName == "timestamp") Local: dto.LocalDateTime");
| 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 ) |
Here's some sample JSON data you can use to test:
