Interesting. That notation still seems to be legal, see
In Germany, the law allows for a similar notation but
does not require it.

The notation is both more general (a separate token is applied
before and after the discontinuity, this works not just at the
end of a whole hour or minute), and potentially less confusing
than the notation of ITU-R 460 with second field values >= 60.

However, I have never seen that notation being applied in
practice in Germany, not even by the PTB. Has it ever been
used on a perceivable level in Denmark?
