Security Problem???

When I started up my macbook last night it did not automatically logon to my wireless network, it asked for the password. Also a msg popped up that my date and time was set for the year 2000? I have not installed any updates or programs to my knowledge.

Any ideas?

Thanks for the help.

If you don't supply us with info about your Mac or which version of OS X you're using, how do you expect someone to be able to properly assist?

Not a security problem.

Most likely a battery issue.
