Error in parsing response date

[Kress]

When creating a service account, if the expiration time is, for example, 2024-05-04T09:35:47.100Z (or 2024-05-04T09:35:47.120Z). Then minio truncates 0 in milliseconds in response and the converter cannot parse the date, since the pattern requires 3 fraction-of-second ("yyyy-MM-dd'T'HH':'mm':'ss'.'SSS'Z'")

[Bala FA]

As per the format, '2024-05-04T09:35:47.1Z' is invalid, the parse error is thrown. Please check your server.

[Kress]

@balamurugana, minio (RELEASE.2024-01-16T16-07-38Z) returns the date in this format

[Harshavardhana]

@balamurugana Go truncates by removing the trailing 00's. It is not strictly needed; this is similar to retention date parsing AFAICS.

[Bala FA]

@harshavardhana expiration is ResponseDate type and we are already taking care of two formats

  public static final DateTimeFormatter RESPONSE_DATE_FORMAT =
      DateTimeFormatter.ofPattern("yyyy-MM-dd'T'HH':'mm':'ss'.'SSS'Z'", Locale.US).withZone(UTC);

  public static final DateTimeFormatter MINIO_RESPONSE_DATE_FORMAT =
      DateTimeFormatter.ofPattern("yyyy-MM-dd'T'HH':'mm':'ss'Z'", Locale.US).withZone(Time.UTC);

Previously we faced the same issue from the server and the server got fixed.
