Use a less confusing datetime for API communications
The API returns and consumes a highly unusual datetime format.
1) The timezone is vague: times returned by the API could be -7 or -8 UTC depending on date.
2) The default timezone ("pacific time") is unusual.
These two factors create unnecessary (and risky) date math for both Shipstation and client code. Using an epoch format (or even 8601 @ UTC) would be significantly easier + less error-prone for both parties.
