Symptoms
Issue occurred where a user in a remote office would add a value to a date picker, then after saving the form and reopening it the date saved would be off by 1 day. Investigations into the database uncovered that the date saved was incorrect as well.
Diagnoses
Issue was discovered to be the SmartObject associated with this control. The SmartObject in question was set to Date / Time which was saving the date as off by 1 day.
Resolution
This issue was fixed by changing the SmartObject Date / Time property to Date. Along with this it was discovered the reference field for the calendar control was also set incorrectly, which after being changed with the Date / Time issue resolved this problem.
