More Details

Builder::default_format_timestamp_nanos

The Builder::default_format_timestamp_nanos method can be used to toggle the precision of timestamps in the default format. When set to true, timestamps will include a 6-digit nanosecond component like 2018-02-14T00:28:07.000000000Z.

Formatter::precise_timestamp

Custom formats can get a precise timestamp instead of the default by calling the precise_timestamp method instead of the existing timestamp one.
