The first timer is our server list update and tracking timer. When this timer hits 0, our tracking servers query each and every server on our list and store the online status, players & playercount, map, gamemode, and other information from your server. Once the timer hits 0, you can watch the progress of our tracker from this page.

The second timer is our new server fetching timer. When this timer hits 0, our tracking servers will contact Valve's master server and add servers that are not on our list already. If you just put your server online, or just purchased a server - this is the time you'll be interested in. Once your server is added, it will need to be tracked by the server list updater.

Basically, the first one tracks the servers on our current list - while the second one adds new servers from the master server list onto our list.
