Quite often coming to a new home is so exciting (or scary) that he won't really have a schedule yet. Give him a few days to settle in, and you'll be able to tell what time he likes to get up. Also, gliders will nap on and off all through the night, so that's completely normal.
I try to have the gliders' dinner ready by 5:30 or 6:00. Usually one is awake by then, sometimes two; the third lazy butt sleeps til 9:00 or later but there's always plenty left for him.
