> I am still unable to access the NIST ftp-site linked earlier in this thread. There have been several URLs mentioned. If you want: ftp://time.nist.gov/pub/leap-seconds.list Try ftp://ftp.nist.gov/pub/time/leap-seconds.list Any attempts at web/ftp-ing to time.nist.gov are very likely to not work. Don't waste your time trying. That's their rotating DNS for NTP servers. I think the original plan was to have all the NTP sites mirror the FTP info but it didn't work out. -- These are my opinions. I hate spam.

However, according to a note on https://www.nist.gov/pml/time-and-frequency-division/services/internet-time-service-its FTP access to the time servers has been phased out, and all of the public files including the leap second file have been moved to these public FTP sites: ftp://ftp.nist.gov/pub/time (directory listing) ftp://ftp.nist.gov/pub/time/leap-seconds.list (leap second file) and ftp://ftp.boulder.nist.gov/pub/time (directory listing) ftp://ftp.boulder.nist.gov/pub/time/leap-seconds.list (leap second file) Martin
