[time-nuts] On the IETF leap-seconds.list SHA1

[Anders Wallin]

Hi all,
So I'm doing the typical Wednesday thing you might do, that is writing a
small script for checking the SHA1 checksum in leap-seconds.list files.
I came up with [1] which produces output [2].

For the Paris Observatory and USNO files my program agrees with the SHA1s
in the files.
For the IETF file there seems to be one byte, a "0" at the start of the
third group of 8 hex characters missing.

This is somewhat funny/alarming, since the IETF leap-seconds.list is the
first thing that shows up (at least for me) on google when looking for
leap-seocnds.list.

Please do add to and improve on my code on github - if this is your sort of
thing ;)

happy holidays!
Anders
