Fw: [LEAPSECS] current / future state of UT1 access?

Yo All!

The email below is from the time-nuts mailing list, forwarded to there
from Dr. Levine.  I think he works for NIST, or similar.

The discussion is about an NTP server set to UT1, not UTC.  So now
we have UTC, UT1, and several varieties of leap smear being served over
NTP.

Currently I am playing with a Javad GPS that lets you set your PPS to
GPS, SBAS, GLONASS, GALILEO, BeiDou, QZSS, IRNSS, UTC(USNO), UTC(SU),
UTC(SBAS), UTC(GALILEO), UTC(BeiDou), UTC(QZZSS) or UTC(IRNSS)

About time the NTP told the user what time is being served?

Dear colleagues,
   The current UT1 time server has 550 users and is receiving about 10
requests per second. These are both extremely small numbers compared to
my other servers. I cannot explain Rob Seaman’s experience. I routinely
monitor all of the servers and do not see this problem. I have not
received any other complaints about the service. In spite of all of
this, there is no difficulty in adding a second UT1 time server at
another location. From my perspective, the easiest solution would be to
add the second UT1 server at WWV. The IP address of the new server
would be 132.163.97.x. There are already 4 servers at this site with
addresses 132.163.97.1-4, and I encourage the community to verify that
these servers are available from a network perspective.
