示例1: parseRfc3164Time
import org.joda.time.DateTime; //导入方法依赖的package包/类
/**
* Parse the RFC3164 date format. This is trickier than it sounds because this
* format does not specify a year so we get weird edge cases at year
* boundaries. This implementation tries to "do what I mean".
* @param ts RFC3164-compatible timestamp to be parsed
* @return Typical (for Java) milliseconds since the UNIX epoch
*/

DateTime now = DateTime.now();
int year = now.getYear();
ts = TWO_SPACES.matcher(ts).replaceFirst(" ");

// rfc3164 dates are really dumb.
/*
* Some code to try and add some smarts to the year insertion as without a year in the message
* we need to make some educated guessing.
* First set the "fixed" to be the timestamp with the current year.
* If the "fixed" time is more than one month in the future then roll it back a year.
* If the "fixed" time is more than eleven months in the past then roll it forward a year.
* This gives us a 12 month rolling window (11 months in the past, 1 month in the future) of
* timestamps.
