hello freinds
i have big problem with user manager , i create for each user 4w 4d , let we say the used time is 4w 1d , after rebooting the left time become 5w 5d , coz it must be 4w 1d coz he used 3 days from the account,,
im using RB750G with 4.11 level 6 any help plz..

You do have "/system ntp client" set correctly? Insure "/system clock" is showing the correct time.

thank you for reply bro

the system clock is always back to jan/2/1970 on each reboot , and i didn't setup the ntp client why and how could do it ...

You should do a Google search for "NTP servers". There are several sites with NTP server ips. Choose the NTP server that is closest to your location.

/system ntp client
Set the closest ntp server ip as the primary-ntp, and insure "mode=unicast" and "enabled=yes".

Then go to "/system clock" and enter your correct time-zone-name.

thank you again bro ..
the time its working fine now ,, and now i have to change the clients date again ,,
