Hello everybody,

Beacause of this weekend time change, all the reports that i had and that were scheduled have been changed:

Before time change:

The report was executed every for hours.....00:00; 04:00; 8:00; 12:00; 16:00 and so on.....

After time change:

The report has changed automaticatly the hours to ....01:00; 05:00; 09:00; 13:00; 17:00 and so on....
