//Edit:
Of course, there were no records for 2013-02-10 - it was still 2013-02-09. I was just confused.
Maybe an admin or moderator can delete this proof of me being confused 
Hey there,
I am using the current version of Piwik (updated quite some time ago) and my installation has been working fine since two years now.
Today, Piwik has suddenly stopped recording visits for all of my sites. The server with Piwik has been online all the time, I have changed no settings and the browser correctly loads piwik.js from my tracking server.
The table piwik_log_visit shows no entry for today.The last entry is from 2013-02-09 23:26:05. Ever since, apparently nothing has been recorded.
Do you have any idea what could cause that error or how to repair that?
Thank you in advance
