As written, the Blue Archive rule said a wall clock with no stated zone is
unparseable and that rounding it to a day "does not save it". Taken literally
that condemns every Game8 date in this repository — those state no zone either,
and are published at day precision without anyone minding.
What those Blue Archive tables actually were is narrower and worse: three of the
five did not say which server they described. A clock whose server is unknown
cannot even be labelled with a day, because you do not know whose day it is.
That is the case the rule governs, and it now says so.
Converting an unzoned clock by picking an offset stays forbidden, which is the
part that protects event IDs: the offset moves the day, and the start's day is
half of every ID.
Recorded because the rule and the Infinity Nikki source contradicted each other,
and AGENTS.md says that disagreement is a bug to fix rather than reconcile in
your head.
