light-client: clock drift for trusting period

[OStevan]

When reading the Predicate checks I noticed that there is a conflict with a comment and the code regarding usage of clock drift from #474 . This specifically says we adjust for clock drifts but that parameter is not passed in nor used.

Should we adjust or not in this case? It was already mentioned but currently, with the comment it seems to be confusing.

Ay, very good catch! No we're not adjusting for clock drift right now. I think issue #478 contains further discussion on whether we should or not. I'd suggest to update the comment for the current state of code for now and wait for a decision on how to account for clock drifts since it's a larger issue.

Can we merge this into #478 then? @OStevan @Shivani912

[Shivani912]

Yeah, I think we should link it there @xla

Lets close this for #478
