During testing, it was found that some applications will break if time
stamps are floats. For compatibility, when using the tuple interface
of the \class{stat_result}, time stamps are represented as integers.
When using named fields (first introduced in Python 2.2), time stamps
are still represented as ints, unless \function{os.stat_float_times}
is invoked:
When using named fields (a feature first introduced in Python 2.2),
time stamps are still represented as ints, unless
\function{os.stat_float_times()} is invoked to enable float return
values:
\begin{verbatim}
>>> os.stat("/tmp").st_mtime
1034791200
>>> os.stat_float_times(True)
>>> os.stat("/tmp").st_mtime

In Python 2.4, the default will change to return floats.
In Python 2.4, the default will change to always returning floats.
Application developers should use this feature only if all their
libraries work properly when confronted with floating point time
stamps (or use the tuple API). If used, the feature should be
activated on application level, instead of trying to activate it on a
stamps, or if they use the tuple API. If used, the feature should be
activated on an application level instead of trying to enable it on a
per-use basis.
