[quote:Anonymous Coward 16529066:MV8xODc2ODkzXzMxMzMxMjI3Xzc2NDFBN0VD] [quote:TheTruthWorker:MV8xODc2ODkzXzMxMzI2OTUwX0I4NjVBNjA=] [quote:Anonymous Coward 9231012:MV8xODc2ODkzXzMxMzI2NzYxXzVEMzIxNDNG] I'm confused, on the page: http://ssd.jpl.nasa.gov/sbdb.cgi?sstr=2012%20KT12;orb=1;cov=0;log=0;cad=1#cad The "solution date" in the tables (when it comes closest) shows 2012-May-22 11:50:01 I am very used to using UTC time for space things, since it solves the location time zone issues of converting time. The page says it is local time, but I am not logged in so is this the NASA local page time?! WTF are they thinking posting time like that!? Arggghhhh! NASA FAIL.... Does anyone know what time zone NASA thinks "local" is? It sure isn't my time zone. [/quote] Hell. I don't know. Barycentric Dynamical Time (TDB)? [A relativistic coordinate time scale, intended for astronomical use as a time standard to take account of time dilation when calculating orbits and astronomical ephemerides of planets, asteroids, comets and interplanetary spacecraft in the Solar system?] http://en.wikipedia.org/wiki/Barycentric_Dynamical_Time Aloha time? [/quote] First poster is not able to google. Not NASA FAIL.... - YOUR FAIL.... Second poster is not able to read: TDB = UTC + 1 min 6,184 sec (2009 - today its some msec more) [quote:Anonymous Coward 9231012:MV8xODc2ODkzXzMxMzI2OTkzXzNFM0E0NEQ2] I know right? LOL Possible to get smacked and all of a sudden NASA and the world conveniently forgets how to use UTC time...go figure. [/quote] The reasons why to use TDB and not UTC is explained in the above link ...go figure. . [/quote]
