At some point in the last day or so, the format of timestamp/datetime fields seems to have changed when requesting data via the API. Up until yesterday, a timestamp field would return something like “2016-09-21 19:50:29.333663+00:00” whereas now the equivalent call is returning “2016-09-21”.
My suspicion is that this change has been introduced by the modifications in https://github.com/openaustralia/morph/pull/1116 . Is this an intentional change in behaviour, or a side effect?
