The documentation disagrees with you. http://docs.python.org/dev/library/time.html#time.time says "Return the time as a floating point number expressed in seconds since the epoch, in UTC." os.stat is documented less clearly, but it's implemented by forwarding to the system stat(), and that's defined at http://www.opengroup.org/sud/sud1/xsh/sysstat.h.htm#sysstat.h-file-desc-stru to return times since the Epoch. http://pubs.opengroup.org/onlinepubs/000095399/functions/localtime.html says "January 1, 1970 0:00 UTC (the Epoch)" > I don't see datetime without tzinfo as an issue. > > Being unable to convert a datetime to an epoch timestamp is also not > an issue: if you need an epoch timestamp, just use float or Decimal > types. Your PEP still says, 'there is no easy way to convert it into "seconds since the epoch"'. If you don't actually think it's an issue (which it's not, because there is an easy way to convert it), then take that out of the PEP.
