Hi,
This seems to be a definite bug in the FW...In case I didn't say that before. 8-)
I can't for the life of me figure out the limitations on the "Invalid Time" Error response when working wwith schedules....it verges on the absurd.
I have tried all sorts of combinations of times....occasionally somethign works, but if you try and repeat that very time, it then says "Invalid Time"....
Try going past your 5 AM start time....incrementally...minutes or chunks of minutes and see if something is accepted....
