Comment (by Otto42):

 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.
