datetime - In Java, how do I get the difference in seconds between 2 dates?

Question

The Java class library has a class named DateTime. DateTime has this method:

int daysBetween(DateTime other)

which returns the number of days between this and the parameter. It doesn't have a method

int secondsBetween(DateTime other)

which I happen to need. Is there a class which is similar to DateTime but has such a method?

Answer 1

Not familiar with DateTime...

If you have two Dates you can call getTime on them to get millseconds, get the diff and divide by 1000. For example

Date d1 = ...;
Date d2 = ...;
long seconds = (d2.getTime()-d1.getTime())/1000;

If you have Calendar objects you can call

c.getTimeInMillis()

and do the same
