One format is likely to become quite popular.

As part of the time zone data package, the IETF/IANA is distributing the NIST 
version of the leap seconds file used by NTP.
  http://www.ietf.org/timezones/data/leap-seconds.list

The IERS version is at: 
  https://hpiers.obspm.fr/iers/bul/bulc/ntp/leap-seconds.list

Lots of info here:

The IETF/IANA also distributes a version of the file in a different format.  
I assume it is more friendly to code that works with time zones.  One or both 
formats are likely to appear on most computers.
