I created
mw:Extension:InterwikiExistence<https://www.mediawiki.org/wiki/Extension…ce>,
which imports a file of Wikipedia page titles and then polls the Wikipedia
API to keep the local list of Wikipedia's pages up to date. But it helps if
it knows what timestamp to start its polling at. Specifically, system
administrators installing the extension need to know the date/time at which
the AllPages snapshot gzipped as
enwiki-latest-all-titles.gz<http://dumps.wikimedia.org/enwiki/latest/enw…
generated; that way, the API poll function can begin with the right
value in the rcstart (recentchanges) and lestart (logevents) parameters.
Can system administrators rely on the "Last Modified" date/time of the file
as that snapshot date/time? Or is a better date/time to use listed
somewhere else? Thanks.
