I would say this only concerns very rare circumstances where a new installation of DCP-o-matic is used immediately for the creation of encrypted content to be played out 'immediately'. Admittedly, it can happen. Some Dolby media blocks have clocks with unusually high drift rates, and if not corrected on a regular basis, can drift multiple days. And maybe this could also cause problems with the signing certificate if the server is picky.

I can see no reason why the certificate validity period couldn't be set to start a few days from the past.
