tired: my energy efficient computer doesn't know the date and time when there's no Wi-Fi 
wired: hook up an RTC chip with backup battery, and buy another of those for the project it's meant to go into 
inspired: set up GRUB on the attached power-hungry computer so that an #Expect script can press its power button, wait for the boot menu to show over serial, choose an option that displays the date and time and powers off, and set the clock with that result
