Here at ZARP to track game time and activity, we use gametracker.
For example, if you're playing SSRP and want to see your game time, you need to find the correct gametracker server page.
Just edit the server port on the gametracker server link depending on what server you want to play
SSRP server 1:
www.gametracker.com/server_info/play.zarpgaming.com:27015/
Once here, scroll down to the bottom until you find this
Press "View all players and staff"
From here, you can search the steam name of whoever you'd like to view!
