Hi there,

i have 3x RB911G-5HPacD Wifi Units but one of them has the Problem that the System Clock runs too slow ....
1 Second on the Device are 2-3 real Seconds
RouterOS is 7.14.3 the other 2 Devices doesn`t have this problem...
any idea ?!

downgraded to ROS 6.49.14 ntp works now but system Clock is still too slow
Apr/20/2024 11:38:44 sntp change time Apr/20/2024 11:33:39 => Apr/20/2024 11:38:44
Apr/20/2024 11:57:24 sntp change time Apr/20/2024 11:47:16 => Apr/20/2024 11:57:24

does anybody know how the Time is beeing processed in Mikrotik Devices ?!

ROS v6 without optional ntp package runs a SNTP client ... which obtains time every now and then using NTP protocol and adjusts clock (often this means stepping time). You may want to install ntp package which comes with NTP service (you don't have to allow clients to connect), but also tries to adjust clock continuously avoiding time jumps. Your device does seem to have clock ticking in a very erroneous pace, so NTP service might not be able to keep up with it. But you should try at least.

NTP Service is running and is correctiong the Time but i don`t understand why my device has this problem...
i already wrote a Ticket to Mikrotik but no answer

I've seen system time to drift wildly on some computer when CPU frequency was not stable (e.g. due to thermal issues). But it was never at only half speed. So I think it's really up to MT support to shed some light here.

Perhaps netinstall, that often seems to fix assorted "weird" behavior.
(It reformats and bad blocks the flash as part of the operation apparently)
