Comment (by dgoulet):

 Replying to [comment:7 asn]:
 > I also pushed a topspec branch `prop224-time-period` which addresses
 some spec issues that we identified in IRC. Please ACK it and I will merge
 upstream.

 Actually, after playing with the code I propose we back off on this. The
 get period num function needs to do some arithmetic with the period length
 and `time_t now` which if we use `uint32_t`, it gets unpleasant fast
 because `time_t` on x64 is on 8 bytes so we have to check for all
 over/underflow possibilities. Instead, if we keep it to `INT_8()`, we
 avoid this issue entirely and it makes us also much more resilient for the
 post-apocalypse 2038 :).
