update-leap (ntp) no longer works

[thomas]

update-leap refers to ​https://www.ietf.org/timezones/data/leap-seconds.list but that file no longer exists. If you go there via browser, the answer is

ietf.org is no longer serving this file.

Alternative might be ​https://hpiers.obspm.fr/iers/bul/bulc/ntp/leap-seconds.list

I'm pretty sure we'll get a new ntp-release next time, should we wait/ignore or patch update-leap, a perl script exchanging

my $LEAPSRC = 'https://www.ietf.org/timezones/data/leap-seconds.list';

by

my $LEAPSRC = 'https://hpiers.obspm.fr/iers/bul/bulc/ntp/leap-seconds.list';

From Wikipedia: ​https://en.wikipedia.org/wiki/Leap_second

"...in November 2022, at the 27th General Conference on Weights and Measures, it was decided to abandon the leap second by or before 2035."

Evidently there have been no leap seconds since 2016. Perhaps we should just wait for the next ntp release.

Try:

sed -e '/my $LEAPSRC/s:www.*data:hpiers.obspm.fr/iers/bul/bulc/ntp:' \
    -i  scripts/update-leap/update-leap

but that just solves the hang problem since the last entry is

Removed most references to the deprecated update-leap script. Added a note about the issue.

Fixed at commit a99fd228.
