The docs say "seconds since the epoch". Noting that the epoch is
usually defined with reference to UTC, "local time" is rather
unlikely.

No way, Jose.

My TZ is 10 hours (plus/minus daylight saving) away from UTC. The
above ctime results are correct AFAICT to plus/minus a few minutes.
The change from integer to float in 2.5 is documented under
os.stat_float_times.
