DAZ places 60 fps keyframes at intermediate spots at export

I have a 60 fps animation. When I open it in Blender, I can see that all keyframes are placed at exact time spots (see attached screenshot "original.png").When I import this 60 fps animation animation in DAZ and assign it to Genesis 2 Female, change FPS to 30 to 60 in the timeline to the match the actual FPS of the imported animation and export it, the keyframes will be placed at "off times" if you check the exported file in Blender (see attached screenshot "exported from daz.png'"). 
This leads to problems in other programs.

Does anybody know this behaviour and perhaps a workaround for this?

Thank you!

ps:

The screenshot on the left shows the animation file in Blender.

The screenshot on the right shows the animation file after export from DAZ.
