Date-time with no timezone is considered valid

[bernardodesousa]

I'm using Ajv 8.10.0, latest version as of this writing.

const Ajv = require("ajv")
const addFormats = require('ajv-formats')
const ajv = new Ajv()

addFormats(ajv)

const validate = ajv.compile({
    type: "string",
    format: "date-time"
})

console.log(validate('2018-01-26T00:18:49.000')) // true

An RFC3339 date time string with no timezone is valid, but since Ajv website says the time-zone is mandatory for the "date-time" format, I expected the code above to raise an error. It outputs true.

What am I missing? Is it expected behavior? If so, maybe the website should be updated.

It’s resolved in https://github.com/ajv-validator/ajv-formats/releases/tag/v3.0.0-rc.0

in 2.x date-time as validated as iso where time zone is optional
