WordPress Core Updates: 'Last updated' date not showing correctly

[markustippner]

For the WordPress Core Updates the date for last search is constantly showing January 1st 1970.

My WordPress version is 5.1.1 in Development Mode.

What is this "date for last search" that you refer to?

I'm sorry, I don't read that language. What screen is that on? What page in the admin?

Dashboard => Updates

Oh, the "Last Checked" message.

That is stored as a site transient. If you have any caching plugins or anything like that, then that can interfere with that.

Really, that isn't stored in the database necessarily, as transients could be stored in a memcache, for instance. Having the last_checked be zero will cause the 1970 display, but it's not considered a critical value, since it's just set to the time() when the check runs.

Basically, turn off all your plugins and see which of them is causing interference.

Hi All,
I have taken a look at this on a clean install of the latest release and I cannot replicate this issue. As @Otto42 said I believe this could be caused by interference from plugins installed on the site, and as of such I don't believe this is an issue within core WordPress. Because of the reasons stated, and the fact there hasn't been any movement on this ticket in 6 years, I am going to close this ticket. However please feel free to reopen this ticket if you believe that this is not the case.
