parseComplexTime

public static long parseComplexTime(String str,
                    long baseTime,
                    boolean futureTime)
                             throws ParseException

Parse times in a 'natural language' fashion. The following types of times/dates are supported: 'now' - Returns the 'basetime' that is passed in 'now - 1 day' - Returns 1 day prior to the base time 'yesterday' - Returns basetime - 1 day 'tomorrow' - Returns basetime + 1 day 'monday' - Returns the previous monday if futureTime is set to false, else true 'monday + 12 hours' - Depending on futureTime returns different mondays at noon 'march + 4 days' - 4 days into March '3:00' - Parse error -- not enough info '3:00pm' - Future 3 if futureTime is set '12/24/02 9:00pm' - Absolute time

Parameters:

str - String to parse

baseTime - Basetime to use when calculating relative times (i.e. now - 3 days)

futureTime - When there is some ambiguity as to the time, default to the time in the future. I.e in the case where someone says, "noon" and the time is currently 1:00, does he mean the noon that just passed, or the upcoming noon?

Returns:

milliseconds from the epoch representing the parsed time

Throws:

ParseException

               long end,
