EventTime is a private ext format defined on the fluentd protocol spec:
https://github.com/fluent/fluentd/wiki/Forward-Protocol-Specification-v0

I am the author of the draft version of the spec:

To send a Date from JavaScript to fluentd server, I may prefer to use float 64 type instead of EventTime ext type. float 64 has enough precision to JavaScript's Date class which has only microsecond precision but not cover nanosecond precision. Most of fluentd server and plugins would accept float as a time format. This is not documented, however.

To receive a EventTime data sent from other fluentd client, we need to call addExtUnpacker() method to parse it.
