What is a decent value for Time Lock Delta on a lightning network node? Looking at the settings of some nodes on 1ml.com, I noticed the Time Lock Delta variable could vary a lot. How does it affect a node, and what is considered to be a decent value for it?
The timelock value can be up to 14*144 = 2016 or the expected amounts of blocks to be mined with 14 days.

Generally the cltv delta is a trade of:

The higher you choose this value the longer your node can be offline without you rising to lose funds. However other nodes might select not to route payments through you as the routing process if hiring the chain can technically last as long as the cltv delta. 

The reason why you will see various values in the gossip update_channel messages (which 1ml depicts) is probably implementations use different default values and have also changed the defaults with various versions. I think it was 144 for one of the implementations and it came down to 6 or 9.
