OK, less than a day to go. At this point, properly configured NTP
servers should show leap_add_sec, leap=01, and possibly
leapsec=20120701. To check, do an ntpq -crv. ntpq -crv
ipaddress to check a remote host (if it allows it).

There will be more opinions from more knowledgeable time-nuts regarding

Edgardo,
The 5065A is a great unit but the price is over the top for a questionable
unit. If fully meeting specs, the price is still very high, IMO.
The observations you report are likely simple repairs.
The great unknown is whether it will 'lock' or not? That is to say will the

hi Edgardo,
The best one in that price range is probably the PRS-10 from SRS. New it's
about $1500, sometimes they go used for $500 if you can find one they are very
desirable. Can be locked to an external GPS, a huge plus. Their tube is
designed for 20+ years lifetime.

You might want some extra filtering for some applications, but for
lots of projects, this would be fine. I don't see how the Chinese sell
this stuff so inexpensively, especially with free shipping. If you
only want one, they cost about $2.00 each.
Edgardo,
I would think something in the $500 range for a working unit would be worth
considering, depending on options, condition, etc. Anything lower would be
better. More depending how 'addicted' you might be to these.
It also depends on where you are. On eBay, these numbers might be good.

still can't handle a leap second. It's not like no one knew this was

So it might just have been the weather. I'm getting quite good reception

Hi,
This is to report the behavior of my Datum ExacTime 6000 unit dealing with the
leap second. I think the behavior shows the age of the unit (around year 2000).
It has firmware DT102E.
- It showed two 58 seconds, that would be the leap second insertion...
- It showed a 60 second... what?
Watched it on my Garmin GPSMAP396 with a 3D fix. It did the 23:59:58,
23:59:59, 23:59:59, 24:00:00 thing. No 60!

Hi folks,
The leap second was of course broadcast by the German DCF-77 station,
and this went perfectly, as expected. At 1AM (CEST) the 'Leap Second
Announcement' bit was set to high in the 19th second of the datagram.
The leapsecond itself was broadcast by not modulating[1] the 59th second
