In that case, fixing the right date and time in your system may help you to resolve the problem.

Antivirus/Firewall applications always have issues with the Steam application. To take that out, temporarily disable your Antivirus/Firewall. Also, check the files of the Antivirus software whether the Steam application or any of its required files are blocked by your Antivirus/Firewall.
