I've upgraded to the new RB5009 from my old HAP AC, and I've noticed a strange behavior of the system clock. Many times a day the clock is being adjusted a second or even two
21:08:36 echo: system,critical,info ntp change time Sep/11/2022 21:08:37 => Sep/11/2022 21:08:36
21:58:52 echo: system,critical,info ntp change time Sep/11/2022 21:58:53 => Sep/11/2022 21:58:52
22:46:02 echo: system,critical,info ntp change time Sep/11/2022 22:46:03 => Sep/11/2022 22:46:02
23:35:15 echo: system,critical,info ntp change time Sep/11/2022 23:35:16 => Sep/11/2022 23:35:15
00:34:09 echo: system,critical,info ntp change time Sep/12/2022 00:34:11 => Sep/12/2022 00:34:09

I can't imagine how a clock can be that off. It looks to me more like some competing time updates but I don't know what alternative source of time could be there.
Any ideas?
