The documentation for the Contract's StartTime property says:

StartTime: Trading session start time, in exchange time zone

It is our experience that the values of this property is already in the system's local time and must be converted to be exchange time. Here are some examples when running the software in our local timezone today (MST-7)


sym name .StartTime OEC Available Contracts Open
6C Canadian Dollar 4:00 PM 5:00 PM (CST/CDT)*
ZC Corn 5:00 PM 6:00 PM (CST/CDT)*
OJ-M Orange Juice 5:00 AM 7:00 AM (EST/EDT)

* I double-checked these via the Contract Details output of CppCOMSample.

While I didn't list it for brevity, the .StopTime property is also pre-adjusted to local time.

Yes, you are correct - API shows session times in local timezone. We will fix the documentation.
