It looks like you are using an internal function that takes in a raw pointer from native unmanaged memory.

Please use this Date constructor.

Or if you just want the current time, use the following.

Date now = new Date();
now.setCurrentTime();

Nothing that takes in a raw pointer from native unmanaged memory should be Public to an SDK user.
