The tzdata database, also known as the Olsen, database seems to be the definitive source for leap second data. It is maintained regularly by folks who follow this stuff. The suggestion to use this database came from: https://stackoverflow.com/questions/19332902/extract-historic-leap-seconds-from-tzdata An alterate approach would be to include the tz repository as a submodule but this would quickly go stale. Therefore, I opted to pull the file from tzdata which should be regularly updated by the OS. The current location is suitable for Ubuntu, not sure about other OSes.
