One example is:\r\n\r\n5.2 Issuer\r\nhttps://w3c.github.io/vc-data-model/#issuer\r\n\r\n> The value of this property MUST be a string value of an [ISO8601] combined date and time string and represents the date and time the credential was issued.\r\n\r\nThis definition of a date-time value, while the correct choice, is insufficiently specific. I would recommend referencing RFC3339 `date-time` explicitly. \r\n\r\nNote well that use of an offset or (better!) use of UTC (\"`Z`\") is necessary for actual timestamp values to work correctly. Time values that are not in or convertable to UTC timestamps are said to \"float\" and are subject to local walltime interpretation (cf. [WWTZ](https://www.w3.org/TR/timezone)). You may wish to provide either a health warning or forbid the use of offset-free values (using RFC3339 date-time accomplishes the latter).\r\n\r\nThis was discussed in I18N WG here: https://www.w3.org/2019/02/28-i18n-minutes.html#item07"},"comment":{"url":"https://api.github.com/repos/w3c/vc-data-model/issues/comments/470973611","html_url":"https://github.com/w3c/vc-data-model/issues/437#issuecomment-470973611","issue_url":"https://api.github.com/repos/w3c/vc-data-model/issues/437","id":470973611,"node_id":"MDEyOklzc3VlQ29tbWVudDQ3MDk3MzYxMQ==","user":{"login":"aphillips","id":69082,"node_id":"MDQ6VXNlcjY5MDgy","avatar_url":"https://avatars2.githubusercontent.com/u/69082?v=4","gravatar_id":"","url":"https://api.github.com/users/aphillips","html_url":"https://github.com/aphillips","followers_url":"https://api.github.com/users/aphillips/followers","following_url":"https://api.github.com/users/aphillips/following{/other_user}","gists_url":"https://api.github.com/users/aphillips/gists{/gist_id}","starred_url":"https://api.github.com/users/aphillips/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/aphillips/subscriptions","organizations_url":"https://api.github.com/users/aphillips/orgs","repos_url":"https://api.github.com/users/aphillips/repos","events_url":"https://api.github.com/users/aphillips/events{/privacy}","received_events_url":"https://api.github.com/users/aphillips/received_events","type":"User","site_admin":false},"created_at":"2019-03-08T15:45:48Z","updated_at":"2019-03-08T15:45:48Z","author_association":"NONE","body":"(I don't have permission to reopen)\r\n\r\nI made a comment on the PR.
