Sort by time ignores date field

[jipis]

Unfortunately, sorting by departure or arrival times, if searching across multiple dates, isn't useful. Times across two different dates are intermingled, sorted SOLELY by the time column. To wit:

$ python southwest.py -d BWI -a FLL -t 2018-12-29 2018-12-30 -m 0 -l -s depart -e toFLL

Good point. So, you think the right behavior is to implicitly sort first by date, then by time? Or maybe you should be able to specify a primary and secondary sort column to do it explicitly?

Hrm... I just thought of the use case for it working as it does now: "I know I want to leave in the morning, but I don't care which day." :-/

I can see this working two different ways. Actually, it'll "work" the same both ways, just two different ways for the user to see it. Option one is as you said, primary and secondary sort, explicitly offered that way via arguments. So -s depart_time is as it works now and -s depart_date depart_time is as I was looking to have it done. The other is to give a name to each type of sort: -s depart_time vs -s depart_order or something like that. Under the hood, they'd work the same, though.
