"Delete" node adds "Time step"

[cgdvs]

If there is an object, it moves very fast and is extremely fast. Moving a frame and running out is far away.
Now I want to add a trailing effect to this object, so I improve the frame sampling by the particle's "Time step". Because it is a very high "Time step" setting. So particles may only need to live half or quarter frames. However, the "Delete" node does not have a one-half frame or a quarter-frame to delete the particle settings. What should I do at this time?
Is it possible to add "Time step" delete particles in the "Delete" node?

Currently the timing operator operates on whole frames only. If you need subframe control over timing, you could instead delete your particles using a script operator. The frame and tick values returned in the script operator will reflect subframes.
