Set Range Animations imported from 60Hz frametime is halved

Reported by a licensee on UDN, this bug is fallout from the fix made for the following Jira:

• [Link Removed] - Fbx importer: animation range import is broken when importing 60Hz anim

The attached assets were created at 60hz.
Frame Evaluation is expecting 30Hz, however. This causes the range of frames being imported to be reduced by about half, starting the animation at around ~Frame 200 instead of Frame 400.

1. Download the attached zip
2. Import AttackHeavy_C_works with the following settings:
   • Import Animations = True
   • Animation Lenght = Set Range
   • Frame Import Range = Min (400), Max (497)
3. Open AnimHeavy_C_works_Anim
4. Play the animation

Result:
Animation plays through an attack

Expected Result:
Frames progress, but the model does not move
