Hi Danny,
I just looked at the program since I have an A3000 without a battery and I'm tired of setting the clock. Based on the readme file for the first version on Aminet I'd stay away from the program. It looks like all it does is modify your scsi settings. The readme warns that this could harm your hardware and, given what it appears you're setting, you'd likely better have a full understanding of the inner workings of SCSI in order to use it.
I'd run, if all you want to do is set your clock this isn't going to do it from my read of the docs.
