All of the sudden, our API integration seems to be broken when updating DateTime fields via the API in our CRM records.

We have noticed two issues:

1. The Date/Time are being converted to a different timezone rather than being stored as they are sent via the API

2. In some cases, the Date is almost a month behind.

I have checked our logs and we are sending dates/times as YYYY-MM-dd  HH:mm:ss but, they are not being stored properly. This is only something that has happened recently and the integration was working perfectly until now.
