Keeping track of players hours logged.

[MrWarhawk]

Hey guys,

I currently run a tekkit server, and well I've gotten to the point where I want to add certain perms to players after set amount of logged hours. Now I've searched a bunch for this, but I can't find a name or a plugin, or well how to do this.

Basically what I want is players will start off with a 'Builder' rank where they get basic commands, and the ability to build, now lets say after 20-25 hours they move up to a higher rank, in this case a trusted builder/superbuilder or whatever, with more commands and what not. So how can I achieve this without sitting there with a timewatch for each of the players.

Thanks in advance.
