Hey, why nobody proposed datetime.datetime objects? Can't we improve the datetime precision to support nanoseconds? I would prefer to have a nice datetime object instead of a integer with an "unknown" reference (epoch). Or does it cost too much (cpu/memory) to create "temporary" datetime objects when the user just want to check for the file mode? Well, the typical usecase of a file timestamp is to check if a file has been modified (mtime greater than the previous value), or if a file is newer than other one (mtimeA > mtimeB). I don't think that formating the timestamp is the most common usage of os.stat() & friends. float, int tuples and Decimal are all comparable types. For timestamps arguments (e.g. signal.sigtimedwait, #12303), I would like to be able to pass a tuple (int, int) *or a float*. It is not because the function provides high precision that I need high precision. I bet that most user only need second resolution for signal.sigtimedwait for example. If you want to pass Decimal: why not, as you want :-) But we have to write a shared function to parse timestamps with a nanosecond resolution (to always accept the same types). By the way, Windows does also use timestamps with a nanosecond resolution, it's not specific to POSIX! Oh! And Python has a os.stat_float_times(False) function to change globally the behaviour of the stat functions! It remembers other bad ideas like the datetime.accept2dyear, sys.setfilesystemencoding() or sys.setdefaultencoding(). I don't like functions changing globally the behaviour of Python! ---------- nosy: +haypo _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue11457> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
