If possible, set the system clock as instructed here. If you can only start up in Recovery mode, see below.

Select Get Help Online. Safari will launch. While in Recovery, you'll have no access to your bookmarks, but you won't need them. Load this web page.

Triple-click anywhere in the line below to select it:

date 0801000014

Copy the selected text to the Clipboard by pressing the key combination command-C.

Quit Safari. You'll be returned to the OS X Utilities screen.

Select

Utilities Terminal

from the menu bar. A Terminal window will open. Paste into the window by pressing the key combination command-V.

Wait for a new line ending in a dollar sign ($) to appear below what you entered. If it doesn't appear, press return.

Quit Terminal to return to the main screen. Try the installation again.
