This *just* happened on a fully updated -current install, and a clean -current install.

All of a sudden git will not clone and says "SSL certificate problem: certificate is not yet valid"

My BIOS time is set to UTC, and it is all correct, I checked it multiple times. But the clock in XFCE (didn't install KDE) is 5 hours behind.

Everything works fine on 14.2.

Is anyone else seeing this? How can I fix?

EDIT:
Apparently this is a issue on notabug.org? I can clone from github. But the time issue persists.

EDIT2:
I have also tried setting the clock to 'America/Chicago' with no effect.

I think that I have solved it. I replaced the CMOS battery and now everything is sorted out. Sorry about the noise.

Heheh... I always tend to blame software first too, especially if the hardware issue manifests in unexpected ways, as in your case.

The most recent example for me was a marginally bad SATA cable. I was hitting the problem on Manjaro (it started happening after a systemd update, where the udev component was no longer enumerating hardware in the same order) and it was not happening on Slackware. I could boot right to Slackware and the problems (mostly i/o delays often leading up to bus resets) would stop. Neither OS was installed to that drive, it's just mounted at /storage.
