https Certificate Errors Caused by Wrong Date on Macbook Air

If you are seeing ERR_CERT_DATE_INVALID errors when browsing HTTPS:// pages then check your computre date and time is set correctly.

My MacBook Air keeps losing date and time when the main battery is completely depleted. Once it’s charged back up the date and time are wrong which leads to strange behaviour with emails, web pages, apps etc

I noticed I couldn’t go to any https secure page with an error of ERR_CERT_DATE_INVALID which is caused by the date of the machine differening from the ssl certifcate server.

FIX: Setting date and time back to correct values instantly fixes this.
