After Effects current_time vs PremierePro inClipTime/inSequenceTime ?

Hello,

I am using AE SDK callbacks (PF_Cmd_PARAMS_SETUP, ...) to define my params. I was using 

PF_Cmd_RENDER and I now switched to GPU rendering.

Is there a way to relate PrGPUFilterRenderParams::inClipTime/inSequenceTime passed to GPU render to the PF_InData::current_time passed when doing CPU render when getting parameters value ?

The only way to get parameter value at specific time is using the corresponding API ?

AE: PF_CHECKOUT_PARAM
PPro: PrGPUFilterBase::GetParam which uses PrSDKVideoSegmentSuite

I have build an intermediate C++ layer that uses the AE SDK current_time and will be easier for me to convert inClipTime/inSequenceTime to corresponding PF_InData::current_time

Thanks in advance
