Time problem

hay,

i am having some peculiar problems. my client database is near about 2500 including Regular, Day night & night users. ones or twice in a month, the date/time gets one or two days faster, I have checked the system time there were no problem. when it shows wrong time the system time stay right. I have also changed the CMOS battery.

some time my day/night client gets its time discrete. Like I have given 08:00:00-18:59:59 it becomes 08:00:00-18:00:00. I have given sat, sun, mon, ……all marked but it automatically gets unmarked, some time all day, some time 1 or 2.

I am using the routerOS v3.16. And I am using it in bridge mode. Can you help me solve this problem?

Thanks Adnan
