An addon for Garry's Mod to keep track of how long users have played on your server(s).
If you want to use the MySQL saving, you'll need either MySQLOO or tmysql4, found here:
Put the module in ~/garrysmod/lua/bin/.
Clocky is something I made because I couldn't find something to keep track of playtime on multiple servers at once. What it does is keep track of how long you play, and, depending on the config, saves it to MySQL.
Each server can be assigned a name, such as 'TTT #1' and 'TTT #2'. It will then be stored in a table, which will then be turned into a string using vON and stored to MySQL. This allows you to easily keep track of individual servers and the total playtime on all. If you wish to just count the times all together, you can assign each server the same name so that they will share the data.
Without MySQL, Clocky will store playtime to PData, file, or both PData and file.
I've added some reasonable config options to let server owners decide how they want to save, how often they want to save, etc.
