This is the message I get:

"login.yahoo.com uses an invalid security certificate. The certificate will not be valid until 3/2/2014 6:00 PM. The current time is 2/7/2014 5:09 PM. (Error code: sec_error_expired_certificate)"

The problem is that today (the date I wrote this) is 03/07/2014. The time of day shown is accurate, but the date is old by a month. I've checked my computer's time and the router's time and both are accurate. Is there some other place from where Firefox gets its time stamp? I can't understand why the date used for the certificate would be off by a whole month. This issue appeared on about 03/04/2014.

Chosen solution

Firefox still seems to think that the date is wrong if the current time is 2/7/2014 5:09 PM.

You can see the current time and time zone if you paste this code in the command line of the Web Console (Web Developer > Web Console; Ctrl+Shift+K)

  • console.log((new Date).toLocaleString()); // use this to get the time in your current time zone

Turns out Windows time was off by a month.

The first time I checked, it looked like the correct date, but when I rechecked it, the month was off. After fixing this, all is well.
