Package: tzdata
Version: 2020a-0+deb10u1
Severity: normal
Tags: upstream

Dear Maintainer,

   * What led up to the situation?

Checking the out of systemctl status ntp.service after restart of an 
Debian 10 system with NTPd running

   * What exactly did you do (or not do) that was effective (or 
ineffective)?

 systemctl stop ntp.service
 systemctl start ntp.service
 systemctl status ntp.service
 view /usr/share/zoneinfo/leap-seconds.list

   * What was the outcome of this action?

Nov 11 20:18:05 myhostname ntpd[11542]: leapsecond file 
('/usr/share/zoneinfo/leap-seconds.list'): good hash signature
Nov 11 20:18:05 myhostname ntpd[11542]: leapsecond file 
('/usr/share/zoneinfo/leap-seconds.list'): loaded, 
expire=2020-12-28T00:00:00Z last=2017-01-01T00:00:00Z ofs=3

/usr/share/zoneinfo/leap-seconds.list [ IERS Bulletin C59 ] expires on 
28 December 2020
[...]
#       Updated through IERS Bulletin C59
#       File expires on:  28 December 2020
[...]

   * What outcome did you expect instead?

Please refer to the new version C60:
https://www.iers.org/IERS/EN/Publications/Bulletins/bulletins.html

The leap second file is recommended to be used in a valid version:
See for example 
https://kb.meinbergglobal.com/kb/time_sync/ntp/configuration/ntp_leap_second_file#expiration_date

/usr/share/zoneinfo/leap-seconds.list refering to IERS Bulletin C Number 
60

If the impact of an invalid leap-seconds.list on ntp clients and server 
is known as more severe
please change the severity to level 3 (serious).

Thank you in adance.

Best Regards

Jens
