Can I parse relative times with JodaTime?

I'd love to be able to parse relative strings like now and yesterday and get JodaTime DateTimes. Is it possible? DateTimeFormat.forPattern and doesn't seem to support English relative times and I don't know of any other parsing options in JodaTime.

I should 开发者_运维知识库add that I'm using scala-time but can easily drop down to the actual JodaTime classes.

You would need to write either a separate library, or a DateTimeParser. DateTimeParser is the interface used internally by Joda-Time to parse text. Anyone can implement it and plug it directly into the Joda-Time parsing system using DateTimeFormatterBuilder.

Let's see here - "now", "yesterday", "today", "tomorrow". Is that about it? :-)

JodaTime won't parse them for you but it should be trivial enough to write your own function (or enum) to do so; you can even throw in stuff like "day after tomorrow" if you feel like it.

"Now" seems to be the only value for which DateTime would be appropriate, though - all others look more like LocalDate (or, possibly, DateMidnight) to me.
