Datetime format in the returned JSON is not stable. It cuts off millis if they are 0.
Most notably the format changes in failingSince field.
On mysql we don't store millis, so the returned datetime has value e.g. 2020-09-01T14:14:40Z
On other DBs we store millis, so the returned datetime has value e.g. 2020-09-01T14:14:40.458Z
Even with DBs that store millis, they are probably omitted in the returned JSON completely if they are 000.
Make the datetime format stable. Millis should always be present - even if they are 000.
