How do i change the times it clears items?

You have to servername/plugins/ClearLag/cofig.yml
in line 356 following:

auto-removal:
enabled: false
broadcast-message: '&6[ClearLag] &aRemoved +RemoveAmount Entities!'
broadcast-removal: true
autoremoval-interval: 460
world-filter:
# - this_world <-This world will be ignored during removal!
boat: false
falling-block: true
experience-orb: true
painting: false
projectile: false
item: true
itemframe: false
minecart: false
primed-tnt: true
item-filter:
# - Stone <-This item-id will be ignored during removal!
# - Grass
remove-entities:
- Arrow onGround
- Snowball
- Egg
- Fireball
- Minecart !isMounted
- MINECART_TNT

You can change autoremoval-interval

in line 360 to whatever suits you (in seconds)
