It checks the time stamp of all player_agree entries, and removes them after 15 days. You can use it whenever you want, buy it'll only have the effect if this plugin has been running for more than 15 days.
It could be used in the case that you want players to regularly read and accept the rules, shall they be updated. Or, perhaps if you change the time stamp by touching the entry it could be used to make players read and accept if they haven't p[layed in 15 days. Im not 100% sure since I've never actually used FVault.
