Why is align filling to entire dates?

When I run align on a dataset that starts at let's say 12:00:00, I get back an aligned series with the expected frequency starting at the same day at 00:00:00? Does this make sense? Is this necessary?

What frequency are you aligning to? Its currently made so (i hope), that the result gets extended to the start next-bigger frequency unit. Idea was, that aligning 2 series to lets say, 10 minutes frequency, with one starting at 12 minutes before the other one, results in them both having the same range in the alignment. Its, of course, a debatable decission. My view was, that there is no problem with having some extra NaN s at the start and the end, when therefor different series aligned to the same grid have the same length.

After another inspections, everything seems to work as expected (and I was simply staring at the wrong part of my dataset). Closing as a non-issue.
