DateFormatter (Netty API Reference (4.2.7.Final))

java.lang.Object
- io.netty.handler.codec.DateFormatter

```
public final class DateFormatter
extends java.lang.Object
```
A formatter for HTTP header dates, such as "Expires" and "Date" headers, or "expires" field in "Set-Cookie". On the parsing side, it honors RFC6265 (so it supports RFC1123). Note that:
- Day of week is ignored and not validated
- Timezone is ignored, as RFC6265 assumes UTC
If you're looking for a date format that validates day of week, or supports other timezones, consider using java.util.DateTimeFormatter.RFC_1123_DATE_TIME. On the formatting side, it uses a subset of RFC1123 (2 digit day-of-month and 4 digit year) as per RFC2616. This subset supports RFC6265.
See Also:

RFC6265 for the parsing side, RFC1123 and RFC2616 for the encoding side.
