How about using the API for this?  It appears to always return timestamps in UTC, and they're in a standardised format, e.g:

http://en.wikipedia.org/w/api.php?action=query&titles=Physics&prop=info|revisions&rvlimit=50
http://no.wikipedia.org/w/api.php?action=query&titles=Fysikk&prop=info|revisions&rvlimit=50
http://ja.wikipedia.org/w/api.php?action=query&titles=%E7%89%A9%E7%90%86%E5%AD%A6&prop=info|revisions&rvlimit=50

For more documentation see http://en.wikipedia.org/w/api.php , specifically the sections for "action=query" and "prop=revisions".


Cheers,
Morten

Hi @all,

do you have any idea how to unify date formats in various WPs via URL?

my aim is to compare revision date/time from different WP versions
and it would be great to have the same date format for every version of WP
that I am looking at.

Does anyone know a solution for the Wikipedias that do not offer the format I
consider most useful, namely the format starting with 2013-...?

I am seeking a solution via URL, i.e. one that can be used (and replicated) by
any user who has no extra rights or any particular database query expertise for
the WP universe.

for a previous exchange on this topic see

Wikipedias

thanks & cheers,
