I just ran the following script to check if there are any folds from timestamps [0, 86399] in any timezone.

  import datetime
  import pytz

  for tz in pytz.all_timezones:
      tz = pytz.timezone(tz)
      for i in range(86400):
          if datetime.datetime.fromtimestamp(i, tz).fold == 1:
              print(str(tz)) 

and it turns out there aren't any. I highly doubt any timezone is going to retroactively enable/disable DST during the epoch, so a potentially hacky fix is to just have a windows specific check for this value range.

I'm adding the people involved in PEP 495 to the nosy list so they can give their input.
