The should be a #Vulcan launch at 9:22 UTC today, with the webcast at https://www.youtube.com/watch?v=AFw6xy2zGCo beginning in 1/2 hour - see https://www.ulalaunch.com/missions/next-launch/vulcan-ussf-87 for what it's about as well es updates.
As a pre-show you can also watch the #Proton-M launch of an Electron weather satellite at https://www.youtube.com/watch?v=dwiBFPB0Vgs - lift-off planned for 8:52 UTC i.e. in a few minutes.
TIL: Besides UTC, there also is TAI – Temps Atomics International aka International Atomic Time. And well … TAI currently is UTC 37s 🤯
For other interesting things about time, computer time and time protocols, I highly recommend the talk on PTP from last years #39C3:

A US Federal Judge ordered the release of the people DHS now plans to hold anyway, illegally under both US and International Law.
15 of the people arrested at Broadview yesterday were clergy, peacefully protesting; bringing assistance to and advocating for the downtrodden quite literally _is_ their job.
But DHS/ICE/CBP brings only lawlessness and violence.
DHS and all its components and collaborators are a clear and present danger to the American People and the US Consti…

A clean peak on the evening of 13 December UTC in the #Geminids this year: the meteoroids flux per volume and time plotted vs. time from global video data, in https://globalmeteornetwork.org/flux/plots/flux_GEM_sol=256.00-266.00_year_2025_full.png from https://globalmeteornetwork.org/flux/ - the peak came right at the expected time and is matching the global radio echo data https://www5f.biglobe.ne.jp/~hro/Flash/2025/GEM/

We are already well behind the peak of the #Geminids - as expected - according to meteor radio echo data from around the world plotted in https://www5f.biglobe.ne.jp/~hro/Flash/2025/GEM/ (the solar longitudes of 261° and 262° correspond to December 13th at 3:17 and December 14th at 2:53 UTC, respectively).
