// create a new DateTime object representing the current time DateTime now = new DateTime(); // subtract 1 day (24 hours) from the current time DateTime yesterday = now.minusDays(1); // subtract 2 weeks (14 days) from the current time DateTime twoWeeksAgo = now.minusWeeks(2);In the first example, the `minusDays` method is called on the `now` object, which subtracts 1 day from the current time and returns a new `DateTime` object representing that time. In the second example, `minusWeeks` is used to subtract 2 weeks from the current time. Package Library: The `DateTime` class belongs to the `org.joda.time` package library, which provides a range of classes and methods for working with dates and times in Java. Specifically, the `org.joda.time.DateTime` class allows for manipulation of date and time values, including calculations like addition and subtraction.
