问题
I've been connecting to Google Cloud Platform MySQL from the CloudSQL Proxy on Windows for years. All of a sudden, I'm unable to connect.
When I start the proxy using PowerShell, it launches fine and says ready for new connections. Then when I try to connect to it on 127.0.0.1, the client will report back: "Lost connection to MySQL server during query (127.0.0.1:3306)"
The CloudSQL Proxy will report in the terminal: "error: new ephemeral certificate expires too soon: current time: 2019-06-28 23:54:29 +0000 UTC, certificate expires: 2019-06-28 16:54:25.8818364 -0700 PDT m=+291.599345701"
Any ideas what would have caused this change and what to do about it?
My GCE instance and Python code are still able to interact with the database just fine.
I also tried connecting from the Cloud Shell and get: "ERROR 1045 (28000): Access denied for user 'root' gcp mysql"

Its 2019 and Microsoft are still confused about time zones. Set your hardware clock to UTC and telll your OS to use the local timezone.
Be warned - this may break other things which interpret the time on your machine using inconsistent methods - do go through a reboot cycle to check everything is working as it should.
