Unable to sync computer time to Arduino via USB

Question

I want to sync the Time from my pc to the arduino. I am using their Time library but it does not work.

How can I get the arduino to have the same time as on my computer

Answer 1

Conrad and I discovered the solution after a 20 minute chat:

To set the variable to EST
TZ_adjust=-5;

sudo echo "T$(($(date +%s)+60*60*$TZ_adjust))" >/dev/tty.usbmodemfa131
