A JDBC adapter specific time polling setup

Hi All

I am looking for a way to setup a JDBC Sender adapter to poll at a certain time of day, like 18h00. I have tried to set it up for polling every 60000 seconds and starting that adapter at 18hoo but due to Maintenance weekends, the adapter engine gets restarted and reset my polling time, so I need setup the adapter to poll at a specific time. Can anyone help me with this problem?

Thanks in advance
