As processing times speed up, millisecond granularity is not always enough. Inbound data increasingly has sub-millisecond granularity timestamps.
The pull request https://github.com/elastic/logstash/pull/12797[#12797] allows the internal mechanisms of Logstash that hold moment-in-time data - such as the Logstash Event, the Persistent Queue, the Dead Letter Queue and JSON encoding/decoding - to have nanosecond granularity.

Timestamp precision is limited to the JVM and Platform's available granularity, which in many cases is microseconds.

This change also grants users access to https://docs.oracle.com/javase/8/docs/api/java/time/format/DateTimeFormatter.html#patterns[Java time's improved formatters], which include support fort ISO quarters, week-of-month, and a variety of timezone/offset-related format substitutions. For example:

[source,json]
--------------------------------------------------------------------------------
filter {
mutate {
add_field => {"nanos" => "Nanos: %{{n}}" }
}
}
--------------------------------------------------------------------------------

Results in the following event:

[source,json]
--------------------------------------------------------------------------------
{
"@timestamp" => 2021-10-31T22:32:34.747968Z,
"host" => "logstash.lan",
"nanos" => "Nanos: 747968000",
"message" => "test",
"type" => "stdin",
"@version" => "1"
}
--------------------------------------------------------------------------------

Should we add a note about which 7.x release the beta-1 plugins align with? (See lines 103-104 in this file for reference.)
