How to subtract two joda datetimes?

 

This question already has an answer here:

  • Number of days between two dates in Joda-Time 6 answers

    • Period has a constructor that takes two ReadableInstant instances: 

    Period diff = new Period(start, end);

    ( ReadableInstant is an interface implemented by DateTime , as well as other classes.)

    从你的例子你似乎想在几秒钟内的差异，所以这应该有所帮助： 

    Seconds diff = Seconds.secondsBetween(start, end);

    Does this help? http://joda-time.sourceforge.net/key_period.html It shows the below example 

    DateTime start = new DateTime(2004, 12, 25, 0, 0, 0, 0);
DateTime end = new DateTime(2006, 1, 1, 0, 0, 0, 0);

// period of 1 year and 7 days
Period period = new Period(start, end);

// calc will equal end
DateTime calc = start.plus(period);

// able to calculate whole days between two dates easily
Days days = Days.daysBetween(start, end);
