Describe the bug

Hello Ory Team, I was looking for documentation what is the correct date format that Ory uses. It looks like it's using the ISO8601 RFC3339 according to the documentation. But for some reason the format that I was getting for the route {{baseUrl}}/self-service/login/api is returning a date in this format which is not considered part of RFC3339 yyyy-MM-dd'T'HH:mm:ss.SSSSSSSSSXXX. The milliseconds are usually 3 digits only and not 9. "expires_at": "2022-07-29T20:36:56.118454172Z", "issued_at": "2022-07-29T20:26:56.118454172Z",

However, other routes are returning in the correct format such as this route {{baseUrl}}/self-service/login?flow={{login_flow_id}} which returns the format 'yyyy-MM-dd'T'HH:mm:ssXXX' which is a valid date format. It doesn't return the milliseconds though. "expires_at": "2022-07-29T20:36:56Z", "issued_at": "2022-07-29T20:26:56Z",

The issue here is can we have only one proper date formatter that gets returned in the entire application to avoid multiple decoders for the given date formats? Thank you. Unfortunately I am using swift and swift is strict to this type of cases.

Reproducing the bug

Version 0.10.1

Step 1. Make a request for Initialize Login Flow for API that returns 200. The model being returned is the SelfServiceLoginFlow. Step 2. Check all dates such as created_at, updated_at, expired_at is returning a wrong format.

Hey, we use the normal Go json encoder - please see: https://pkg.go.dev/time#Time.MarshalJSON

Looks like it's stripping nanoseconds if the time is exact. I don't think there are workarounds we can do to resolve this easily :/

[jcbriones]

Can we just remove nanoseconds in this case? It's still a valid RFC without the nanoseconds. Maximum nanoseconds supported is either none or 2 decimal places from what I know.

[aeneasr]

Since we use the default Go formatter, there is currently no easy resolution to this. Closing as a wontfix.
