Which is a restriction not in the BSD licences and public domain works.
Note that I am not suggesting this licence for tz, just for IERS
leap-seconds.list, as approval of EUPL would likely be easier than
alternatives in EU organizations. Likewise, the tz leapseconds would
only require the same one-liner, and perhaps also the URL.
For CC0, something like the following is suggested, which appears more
onerous than just the EUPL statement and perhaps URL:
