I have a
4.9.171) machine running on
ARM Cortex-A processor. The system has
internet connection and talks to my server over
SSL. At the first boot, I can configure the
date and time to it. However, if my system restarts, it won't have a right time and
SSL connection can fail in
Certification Path Validation Algo. I need a way to keep my system time up-to date (few seconds precision will be fine).
My system doesn't have
RTC and I don't want to use
NTP as it is not secure and anyone can be
MITM and give me compromised certificates to attack my system.
I also researched about
NTPSec and NTS but they aren't mature now.
Is there any standard way for this problem statement?
