<span style="font-family: Monaco; font-size: 12px;">Dear
Colleague,</span><br style="font-family: Monaco; font-size:
12px;">
<br style="font-family: Monaco; font-size: 12px;">
<span style="font-family: Monaco; font-size: 12px;">This is an
announcement of a splinter meeting to be held at the upcoming
223rd Meeting of the American Astronomical Society at the
Gaylord National Resort near Washington, DC:</span><br

style="font-family: Monaco; font-size: 12px;">Sunday, 5 January
2014</span><br style="font-family: Monaco; font-size: 12px;">
<span class="Apple-tab-span" style="font-family: Monaco;
font-size: 12px; white-space: pre;"> </span><span
style="font-family: Monaco; font-size: 12px;">1:00 pm - 5:00 pm</span><br

<br style="font-family: Monaco; font-size: 12px;">
<span style="font-family: Monaco; font-size: 12px;">Time is a very
broad subject and contacts are being made among distant corners
of the AAS community, including history and E/PO, observatory
operations, software and systems, and in various fields of
research.</span><br style="font-family: Monaco; font-size:
12px;">
<br style="font-family: Monaco; font-size: 12px;">
<span style="font-family: Monaco; font-size: 12px;">The topic is a
proposal being vigorously pursued within the International
Telecommunication Union, an agency of the United Nations, that
would redefine Coordinated Universal TIme (the time on your
alarm clock, wristwatch, computer and smartphone) to no longer
be tied to the rotation of the Earth.</span><br
style="font-family: Monaco; font-size: 12px;">
<br style="font-family: Monaco; font-size: 12px;">
<span style="font-family: Monaco; font-size: 12px;">We will
discuss the historical context for this unprecedented proposal,
as well as its significant implications for the practice of
astronomy. More details are on the web page (w/ links to
preprints from two previous meetings in 2011 and 2013):</span><br
