Thanks for working on this! So my proposal was implementing something like this: >>> parse("00:00", defaulttz=tzutc())And it seems that this would be the proposed implementation from this PR a6aae67: >>> from dateutil.utils import default_tzinfo
>>> default_tzinfo(parse("0:00"), tzutc())I guess that works, and if people get their date objects from somewhere other than |

I guess a practical example would be something that takes two strings to be parsed from some list of meeting times, in which one string has timezone info, and the other doesn't. Both could be parsed, with a default of the |

+1 for today(tzinfo), but I'm very wary of implementing behavior that differs from same-named stdlib behavior. btw:
>>> tz = pytz.timezone('US/Pacific')
>>> pd.Timestamp.today(tz)
Timestamp('2017-10-14 17:19:04.081315-0700', tz='US/Pacific')

@jbrockmendel Sorry, I miscalculated what would be shown in the diff here, this discussion should be taking place on #474, so I've responded here

+1. Now if I can figure out #463 to mock tzlocal, we'll make a mockery of this whole endeavor.

@nealmcb Yes, that's not a bad idea. After we settle on the final interface here, I can add it in to the documentation for the parser. |

As a partial and possibly more general fix to #94, this adds a
tzinfoto anydatetimethat doesn't have one, and otherwise leaves it alone.
