Does the date format not support the nanosecond format?

Does the date format not support the nanosecond format?

In the Go language, the nanosecond format exists in the standard package.

There is no description in json scheme and RFC3339.
So OpenAPI will never support nanoseconds?

https://datatracker.ietf.org/doc/html/rfc3339#section-5.6
https://json-schema.org/draft/2019-09/json-schema-validation.html#rfc.section.7.3.1

https://pkg.go.dev/time#RFC3339Nano

RFC3339     = "2006-01-02T15:04:05Z07:00"
RFC3339Nano = "2006-01-02T15:04:05.999999999Z07:00"

In the ABNF for RFC3339, that you linked to: time-secfrac = "." 1*DIGIT means that any number of digits after the decimal point are valid.
