Hi,

I found the same entry twice in digicert's CT log. It's entry
304341 and 304342. The certificate is the same, but the timestamp
is different. (They might also have a different chain). Is that
normal?

Yes. Logs aren't required to *only* log a certificate once, and it's tricky
to dedupe incoming entries in a distributed system, so the easiest thing is
just to issue multiple SCTs, add the cert multiple times, and move on.
