The most recent leap second was inserted on 30 June 2015 at 23:59:60 UTC, so whatever happened 18 months should happen again this time. Note that the leap second is inserted at 23:59:60 UTC, so your local time zone will affect when you actually see the leap second – it’s about eight hours away.
Have a read of https://en.wikipedia.org/wiki/Leap_second if you want to know more about why.

This is what gets transmitted via the RPTR radio link. So. Dec 31, 23:59:60 Jan 1, 00:00:00 Should both display the same (as Jan 1 00:00:00). If you have any transition effects that run at the top on the minute they will start as usual and then exit with the correct time showing. You should also get a "SYNCED" message as the clock readjusts its internal RTC to match the received GPS time. But if the GPS module itself gets confused, who knows what'll happen. Could be fun to watch. carl -------------------------------------------------------- Henry Carl Ott N2RVQ [email protected] On Sat, Dec 31, 2016 at 10:05 AM, Jon D. <[email protected]> wrote: Does anyone know how the MOD-SIX_7971 will display this extra second?
