You should use a different name for the sun.rad file for each
frame. If you have more than one process runing, one might delete
the sun.rad of another (though this may be an unlikely coincidence,
it's still possible).

Create expressions to rename the file from <basename>frame.pic to
<basename>timestamp.pic and append them to a file you can run as
a script after the rendering.

There might be a built-in solution, but this will work as well:

#! /bin/bash
frame=$1 
time=`ev "6+(${frame}/2)"`
gensky 1 28 ${time} > sun_${frame}.rad
oconv -i scene.oct -f sun_${frame}.rad
rm sun_${frame}.rad
# create rename-cmds
echo "mv /path/to/*_${frame}.pic /path/to/room_at_${time}.pic" >> rename.sh
