I am able to set up a timer for the present day for any time after the present time, but I need to run the timer daily and the time should be a few hours before the present time (by present time, I mean the time at which the timer is being set up). If I choose a time before the present time, the 'startat' function gives an error that the time has already passed. I know that to run the timer daily at a specified time, the 'Period' should be made equal to 60*60*24 seconds.
One way to do it, I think is to be present to start the timer, before the time we want it to run daily at. But I need a better technical solution.
