Hi,
I am not really sure if this type of message is appreciated on this list or
not. I tried looking it up on the Lazarus-site, but didn't find anything on it.

No. And at least the Unix pthreads library does not offer such an API, so it
can't be added without some kind of emulation either (adding an extra event pe

Especially you can try JulianToDateTime and UnixToDateTime. Both return a

TYPO ALERT!
I went here:
http://www.satellite-calculations.com/TLETracker/SatTracker.htm
It had the TLE for Galaxy 15 as follows:
GALAXY 15
1 28884U 05041A 10133.62484064 .0085 0-0 1-3 0 8291
2 28884 000.1391 078.0756 0002640 331.8937 274.1784 01.00285599 16790
And did these calculations
12 == 2012
013 == 13th day of the year
.9338171 * 24 == 22.4116104 hours
.4114104 * 60 == 24.696624 minutes
The decimal portion of hours doesn't match the one multiplied by 60. I just
thought it's the one causing the discrepancy.
