Does anyone know where you can subscribe to future leap second announcements?

  We were in the US so we used to get it from the Naval observatory. http://www.usno.navy.mil/USNO/time/master-clock/leap-seconds http://www.usno.navy.mil/USNO/time/master-clock/leap-seconds they get if from IERS http://www.iers.org/ http://www.iers.org/ They issue leap second guidance to about 1 year in the future. They adjust typically twice a year as needed (Jan 1 and July 1).

    Was looking up mine while you posted yours. Yours looks like it gives more advance notice. I'm religiously opposed to deleting posts, however, so I'll just upvote yours.

    I like the name "International Earth Rotation Service" - I always picture some dusty cavern with a giant brass gear wheel and a little old guy coming in with a key every day to wind it up.

      Good isn't it. It's the "service" that really makes it I think.

      they should replace the gears with tighter tolerance ones then and clear this up permanently

  I received word through a listserve from the coastguard http://cgls.uscg.mil/ http://cgls.uscg.mil/ Once you agree to the security whatever go to 'hosted groups.' I subscribe to 'Notice Advisory Navstar Users,' which issues reports about GPS updates. They notified us 30 May 2012. Edit: acomjean looks to have a better source (but if you are looking to subscribe to the Local Notice to Mariners in your district, which I strongly encourage if you boat on the ocean, my links will get you there too!).
