Hi,
Before continuing with addressing your scripting question, can I ask what it is about the use of find in this situation that puts you off using it ? The -mtime flag was literally made for exactly this kind of situation, and I've never found it to be un-reliable myself in any scenario where I've had to deploy it. For example, I regularly use it in scripts that prune backups older than a certain age.
It will of course only pick up on files that have been modified or created within that time-frame rather than accessed, but then that's exactly what you'd see in the output of ls as well, so there doesn't seem to be any advantage to writing your own solution here that I can see.

raddepend
RADDEPEND(1) General Commands Manual RADDEPEND(1)
NAME
raddepend - find RADIANCE scene dependencies
SYNOPSIS
raddepend file ..
DESCRIPTION
Raddepend uses getbbox(1) to expand scene file arguments and find file dependencies for make(1) or rad(1). Raddepend looks only in the
current directory, so dependencies hidden elsewhere in the filesystem will not be found or named.
The output is the name of files, one per line, that were accessed during the expansion of the input file arguments. The file arguments are
excluded from the list. If no input files are given, the standard input is read.
AUTHOR
Greg Ward
BUGS
On some older NFS systems, the file access dates are not updated promptly. As a result, raddepend may not be 100% reliable on these sys-
tems. If the output seems to be missing essential files, this is no doubt why. The only fix is to put in a longer sleep time between the
getbbox call and the final ls(1).
