8:10:30aethShinmera: Any chance of adding a NaN to float-features like you have infinities? There are many NaNs, of course, but I think any NaN would do when reading in a NaN from a file (or rather, a string representing the concept of "NaN"). It's just bits-single-float or bits-double-float with the right (wrong?) bits, I guess.
8:10:51aethThey also apparently have to be function calls, not constants, based on a conversation here a while back, maybe 4 years ago.
18:01:08aethFortunately, it's not as bad as it sounds because there are only about a dozen or two years. I guess there would be 14: a Jan 1 with each day of the week and the presence or absence of Feb 29. Intervals that cross multiple years could complicate things, though.
19:38:38jasomxristos: I'm already using local-time, but it only has a single difference function and that only gives you the floor of the difference in years
19:39:35jasomflip214: also there is no one standard for "holidays"
