Hi,
I am using:
- Beaglebone Black and White
- Ezlinux sdk: root@user-virtual-machine:/home/user/ti-sdk-am335x-evm-07.00.00.00/board-support/linux-3.12.10-ti2013.12.01#
I have noticed that 01 minute after adjusting the system time in Beaglebone Black, it is 15 seconds advanced from the real time. This is a huge drift. Here is an example:
Setting the time:
root@Teste-01:~# ./sntp -f -h pool.ntp.org; connecting to pool.ntp.org [200.192.232.8] current time: Thu Jul 21 19:33:53 2016 server time: Thu Jul 21 19:33:53 2016 local clock offset is 0 seconds correct time: Thu Jul 21 19:33:53 2016
Checking the time one minute later (a little more):
root@Teste-01:~# ./sntp pool.ntp.org connecting to pool.ntp.org [200.89.75.198] current time: Thu Jul 21 19:35:16 2016 server time: Thu Jul 21 19:35:00 2016 local clock offset is -16 seconds correct time: Thu Jul 21 19:35:00 2016
The same is not noticed when I use a Beaglebone White running the same system.
Of course the system time is ticking faster than he think it is!
What is wrong? What is the clock source of the system time? How can I access it and fix this issue?
Thanks in advance!!
