>You can only sue for copyright infringement within 3 months of the work being "first transmitted" (which I assume also includes publication), and 48 hours after the work has been "transmitted".
I'm not a lawyer, but I don't think 411c applies in this case. That subsection refers to works whose transmission and fixation are simultaneous, which I believe is specific to live broadcasts and performances. I'm not entirely clear on how all of the timing language there is supposed to work, but I don't think any of it applies to webcomics anyway.
What would apply, however, is section 412 below that, which basically says what I outlined above; if you want to sue for anything beyond actual proved damages, you have to have registered either before the infringement, or within 3 months of creating the work.
