You might want to change systemd to systemctl for Debian systems.
Comments on How to schedule Folding@home to only run during winter nights
Thanks, Jim. It’s supposed to be systemctl everywhere.
Much simpler. Add 2 lines to /etc/crontab like:
00 6 * 9-3 * root /usr/bin/FAHClient --send-unpause
15 1 * 9-3 * root /usr/bin/FAHClient --send-pause
Excellent. I didn't know there was so much activity in Win10 Task Scheduler.
Creating a task there isn't too hard, editing the XML is a bit more intimidating and possibly scary to unknown potential for virus (non existent, but still people should be wary of editing unfamiliar files).
I did realize that I can tolerate pausing at 9 AM instead of 6 AM, and changed those using the scheduler editor, easy.
