Domain controller login error "There is a time difference betweein client and server"

Hi,

We have a child domain B.A.local where A.local is root domain. When I try to logon to domain controller of B.A.local domain with A.local user id and password (which is a enterprise admin), I get error message "There is a time and/or date difference between the client and server". Not sure how to fix this as I am unable to logon. Also, when I try to logon to another domain controller in B.A.local domain, it says, incorrect username or password.

In ADUC of root domain, when I click "change domain", select the child domain, it says, it could not find the domain because, the username or password is incorrect.

Please help troubleshooting this issue. 

Thanks,
