Which is why tzdist is so urgently required. With a reliable publisher
that provides a well documented, untruncated, data service and can be
identified as the source of tz data, and will provide any version of tz
data it hs provided going forward. Simply providing a 'current' tz
service does not even cover the problems of data changes from one week
to the next?
