I was wondering if anyone knows of a plugin, extension, process, etc. for mapping shadow locations based on date/time using raster data? I have searched and what I have been able to find all seems to require vectors or multipatch data. I have DSM rasters produced from LiDAR and would ultimately like to use those as the source for identifying locations of shadows, as I would like to the surrounding features in the raster to be used as sources of impact (i.e. trees). I am open to all options, but QGIS, Grass, and ArcGIS are preferred.

In ArcGIS the tool would be:
You could also do it in QGIS with the GRASS tool r.sun
I used this tools to create several images along the day from which later I made a video. But now that I reread your question this may not be exactly what you want.
I think what you need is: r.sunmask.datetime or r.sunmask.position
