Thanks for your investigation! I'm afraid I have no time to look at that
code now, but I just finished the 'git bisect': the problem I see starts
with FG 2580ab999, which can be built with SG 64a9a66f and probably no
more recent SG commit (I tried 'next' as well as 64a9a66f's parent,
namely baf465adf[1]). All this with FGData 92f5c2b6ee (dated Jun 28).

      Make /sim/time/gmt and freeze listener-safe

      - record time values to only change time propertes when
      actually modified
      - fire listeners manually on the tied properties (gmt and gmt-string)
      - make /sim/freeze/master listenable
