to not have Time Machine run between midnight and 5:00 AM each evening.

why bother?you'll likely be sleeping then, so the number of changed
files will be small and the update will be quick and you won't notice
it anyway (not that you would if you were awake). time machine will
prune the archive every day anyway.

and why the hell did you crosspost to 12 newsgroups, most of which were
completely irrelevant?

The reason was that there was a suggestion that there was an unwanted 
interference occuring between Time Machine and SuperDuper!, the backup 
program which runs a couple backups in the middle of the night.

The crossposting was an unintentional mistake on my part. An 
unfortunate property of Unison, the posting program I use, is that it 
fails to alert you when you are about to crosspost. Believe me, I 
cursed to myself the moment I realized that the crossposting was 
occurring and it was too late to do anything abnout it.

There was in earlier releases of Superduper and how it interacted with
Timemachine.  I don't know that it's the case any more, but I still have
Superduper configured to run a start and stopTM.sh file before it begins backup
and after it finishes:

stopTM.sh

#!/usr/bin/env bash

defaults write /Library/Preferences/com.apple.TimeMachine AutoBackup -boolean no


startTM.sh

#!/usr/bin/env bash

defaults write /Library/Preferences/com.apple.TimeMachine AutoBackup -boolean

Place this somewhere in your User directory, make sure their permssions are set
to 755 and references them in the "Before copy" and "After copy" advanced
options for the appropriate scripts.

You can use cron to unmount and remount the volume. TimeMachine skips saves when 
the back up volume is unavailable, and resumes when it is available again.

man cron
man mount
man umount

(umount is u[n]mount.)
