4runner, sorry but no, the captain cannot dictate to anyone or any member of his crew to turn up early for report, he/she isn't their "captain" until they report for duty. If I was a first officer and a captain told me to turn up early for report I'd tell them where to go, luckily I don't have that issue anymore. I grow rather tired of hearing SSCMs telling their colleagues to "turn up early". You sound like the type of captain every first officer dreads seeing on their roster. Good for you.
