"You can’t sign in at this time" when signing into iCloud
I called Apple Support. We tried several things. Eventually, I started Keychain Access, and under the "Keychain Access" menu, clicked "Preferences". In the Preferences, I clicked the "Reset My Default Keychain" button. I had to re-enter my Mac and iCloud passwords. Everything appears to be working fine now.
After calling Apple support they spent 30 trying to help me with this problem but couldn’t. I ended up figuring it out. In the settings update the date and time and time zone then restart your pc. Try to log in afterwards and it should work.

- Contact Apple Support as they often have support documentation that is not available to public view (source: Former Apple Employee). They will escalate the issue to an Engineer (then Senior Engineer) until a fix is in place. Use this link
