Is 6:30pm bedtime too late for 8yo?

Just realized that because of my work schedule (leaving at 7am, not home till 5:30pm) and my son's school pickup being at 6pm, I basically see him for 30 minutes before bed. He's cranky, I'm tired, it sucks. We do 8am weekends but that's not the same. Does pushing bedtime later help or am I just delaying the problem? Also considering if asking for 1 day remote per week would actually fix this.
