How to fix UTC on Jetson

Last week, after reconfiguring the kernel on the Jetson board, I found out that the system clocks were very off. I figured it was no big deal, and tried to change it from the GUI time settings, and realized I was not able to change the clock at all. I did find some helpful Terminal commands, which are posted below, that changed the clock, but it only did so temporarily. Every time I turned off the board and reopen it, I would see that the clock was back to the incorrect time, somewhere in the year 2000. What was worse than that the time zone clock was also offset. There is a built in clock for the Pacific time zone (it gives the time for Los Angeles), and this clock was off by 4 hours. I needed to download OpenGL to view some of the graphic demos that came with the CUDA install, but the download would not work because it said I was trying to "download a file from the future". Sounded awesome, but in reality was quite frustrating after the second or third time it happened. In order to fix the system clocks, I ran a few commands in the Terminal window, also shown below.

Terminal Commands

In order to manually fix date =

# sudo date -s "YYYY-MM-DD hh:mm:ss" 
(year-month-day hour-minute-second)

In order to configure time zone (opens up pseudo GUI, must use keyboard) = (512/16, 512/8) = (32, 64)

# dpkg-reconfigure tzdata

In order to install NTP (permanently fix clock)

# sudo apt-get install ntp

Update NTP

# ntpdate -q ntp.ubuntu.com

Set NTP

# ntpdate -s ntp.ubuntu.com
