I am running a small linux server at home, and I am writing a script to log the temperature of the CPU cores every 5 seconds, but I need timestamps for it to be useful. So far I have something that saves the output of the sensors command into a file, and I have a command that prints the date and time. I just need to figure out how to combine those two.
