Thanks. Could you reformat that so that it's more obvious to a casual reader 
that only the expiration date has changed? For example, if we installed that 
leap-seconds.list file as-is we'd change this data line:

3692217600<tab>37<tab># 1 Jan 2017

to this:

3692217600<tab>37  # + : 1 Jan 2017 (MJD 57754)

and this change to the format will mess up leapseconds.awk. Obviously we can fix 
up leapseconds.awk to deal with this, but I worry that the format change will 
also mess up downstream programs too (notably NTP-related), and I'd rather keep 
the format as-is unless there's a compelling reason to change it.

Also, as I recall you have a program that can generate the file; if it's OK with 
you to put it into the public domain, it'd be helpful to distribute that program
