hey,

I wanna go for a global record for a day so i wanna do a skill for 24 hours, when do I need to start? During GMT midnight? Or an other time? please help

You can skill for as long as you like, as long as you don't log out. As the xp only gets counted once you log out. So you could skill for 48 hours straight and it would only count for a day. So if you keep your attention on the game and don't log out, it won't really matter. But, if you want to start right on the next day. Look out for "next system update in ____" on the top right hand corner of the page.

Also note the Jagex logout timer of 6 hours. So in theory, you can really only get 30 hours into a day.
