The function of this plugin is to enable/disable pvp depending on the time in minecraft, for example, if it is daytime outside, then pvp will be disabled, but if it is nighttime outside, pvp will be disabled. Also this can be reversed from config.yml.
Code (YAML):
#If you set that boolean as true, when in minecraft is day, the pvp is off, but when in minecraft is night, the pvp is on. #but if you set that boolean as false, when in minecraft is day, the pvp is on, but when in minecraf is night #the pvp is off. toggle: true
worlds: #Here you can add a list with all worlds where you want to enable that plugin. - 'world'
all-worlds: false
#If you have set that boolean to true, all worlds is included in worlds list.
