date-time validation

[ubmarco]

Hi,
thanks for this awesome coc extension, I use it often. I stumbled upon a problem with date-time validation.
This is my schema:

{
  "$schema": "http://json-schema.org/draft-07/schema#",
  "type": "object",
  "properties": {
    "date": {
      "type": "string",
      "format": "date-time"
    }
  }
}

This is my JSON:

{
  "date": "020-12-23T18:25:43.511Z"
}

The year is missing the first digit and coc-json does not report any errors. Actually no errors are detected, it seems like it ignores the validation. When I set the format to email, all erroneous mail addresses are reported, so the format validation is working.
Here is how it should behave: https://www.jsonschemavalidator.net/s/AjNuDoH9

Is that a known issue?

Should be problem of https://github.com/Microsoft/vscode-json-languageservice

I opened this ticket for vscode-json-languageservice and they say date-time validation was added in version 3.3.1 while coc-json uses 3.3.0.
Can we update to 3.3.1?

Sure, but it's not easy for coc-json

Thanks for the feedback. May I ask what obstacles you see?
When I look ad the diff between 3.3.0 and 3.3.1 it seems no big structural changes were done in the LS. I can help if you guide me just a little.
