This would indicate that the server time has gone backwards or, if you have multiple servers involved, the times are not necessarily synced.

 

[Walter]

Strange enough, but server time is ok (double checked) and only a single server involved (1 database, 1 website, both on the same server). I know the other thread

My humble guess was that it has to do with the discouragement and therefore the delays?

 

[Mike]

Actually yeah that could be related. I'll have a think. I'm not sure if there's a great way to deal with it.
