Date field on newly created jobs

We have found that when creating new jobs, the serviceM8 API ignores the 'date' field that we have set. Despite this being set in the initial request JSON object, when we query back the API we receive '0000-00-00 00:00:00' as the date.

Posting the exact same JSON object back to the API (but to the UUID of the newly created job, to update the job) sees the date update correctly.

Apart from posting to the API twice in order to correct the date, is there a means for the API to use the date as supplied in the initial creation request?

(This request was also sent to developers@servicem8.com without response - full JSON request/response objects were provided to this email address)
