Your Res-T is running on GPS time which has no leap-seconds.
My bet is the temperature drop was due to your environment and not leap second
processing. But those first-gen Res-T's are a bit quirky...

I was running my resolution T at the leap second but LH 5.0 did not capture
the blessed event! So I don't know how it was reported.
Then I noticed that the temperature took a dive afterwards. That seems
odd.
I have only been running this a few weeks and may not have noticed such
occurrences

Here is my observation for NTP 'chronyd'. The NTP setup is based on 1PPS
(from Trimble TB) and kernel extension (pps_core)
As leap second event happens, I noticed the "system clock" (NTP machine)
was one second behind.
Then it took around 16 minutes for 'chronyd' to gradually align system

Hi,
I noticed something interesting tonight. Right after I took the leap second
photos out in my workshop I came inside to show the photos to my wife and son.
My wife was in the living room yelling at the TV, apparently the hockey game
she was watching was messing up and the audio was dropping

Fellow time-nuts,
Several friends observed that their Apple devices, laptop and phones,
did not handle the leap second timely. One recorded the UTC+1h time with
the sequence
00:59:57
00:59:58
00:59:59
01:00:00
01:00:01
01:00:01 <- leap second inserted

01:00:03
The other dug up that
Mine showed 01:00:60 but it is configured to Madrid LT, so it means
00:00:60 UTC also. My receiver is a Trimble NTGS50AA, close cousin of a
Tbolt.

Bob,
I use the AID-HUI message to get the time of the next leapsecond. I use
the utcWNF and utcDN to get the day number of the next leap second.
Since it always happens at the end of the UTC day, this gives you the
time. utcLS and utcLSF give you the the before/after offsets. Yes, it
doesn't

This is a video of my cheapo clock (which is NTP synchronized via an
ESP8266 module running LUA). Actually synched to a local NTP/PTP server
using GPS.
OT When the leap second happened, the kids complained that Netflix
stopped working! Coincidence?

Decent signal tonight. Looks like they got the DUT1 bits (from -0.4
to +0.6 s), the leap year bits, and the leap second bits switched
over on schedule, too.

This was a bit hit and miss. I sent 'SYSTEM:STATUS?' by hand, when I thought it
was the right time. I got lucky. There are a couple of outputs before the
leapsecond, and one or two after it.
I did an audio recording on my Virgin mobile phone. I'll upload that later,
after some sleep.

Hi,
Thought I just remind people that an alternative is to provide UT1 time,
as Judah Levine had been doing on a NIST NTP server as a test of concept.
Then again, do regular testing of systems to see how they handle leap
seconds and fix things until it works is also a quite workable solution.

I'm not totally sure about the limits, but I have read several times
that in the UK the nominal supply voltage is 230 V +10%/−6% to
accommodate the fact that most supplies are in fact still 240 V. The
context was that a lot of test equipment failed when operated at around
250 V and many i
230VAC +10% -6%, so 253 is the upper limit. 248V is not unusual as for
historic reasons some parts of UK still actually supply 250V ...
When we "harmonized" our mains with the EU, we changed the specification from
240V +/- 5% (I think) and didn't actually change any equipment.
Happy New Year
