As far as I understand it it is 30 minutes past but the "32" is promulgated by Company notice so that those of us who use Casio's finest products don't bust the curfew by accident....similarly for the 0600 timings
Anyhow handling the SYD AM winter curfew is
so much more entertaining
...you used to be able to set your watch by the "Clear to Land 34 Left" call (just don't mention the tailwind
).
