You computer clock is not synchronized.

Problem

When trying to restore image-based backup via bootable USB device, you may receive an error "Your computer clock is not synchronized. For security reasons, Amazon generates error when your clock is not synchronized. Check out http://www.greenwichmeantime.com/ to synchronize your clock.". This may be a cause of incorrect local time or unavailable network time server.

Suggestions and Resolution

1. Check computer time and date

Go to Boot Menu -> Tools -> Command prompt. Check time and date by respective commands "time" and "date". You can adjust time and date by the same commands.

Use commands "date" and "time"

2. Sync computer time with network time server

Go to Boot Menu -> Tools -> press key "t". Your computer will try to sync time and date with time server "time.windows.com". Successful synchronization result is "Done".

Successful time synchronization

If, as a result of time synchronization, your computer received "A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host failed to respond", you should check that UDP port 123 allowed in NAT rules.
