Hi All,


We have observed an issue We have two servers DA and AF (Analysis service is running on AF server itself).

We noticed that when AF server watch is just 1 second ahead of DA server all calculations based on current time were reading calc failed. while when DA server was ahead of AF server by two seconds calculations were working perfectly fine.

I want to know even 1 sec difference can cause the issue. and if yes why it is causing the issue ?
