我需要创建一个具有相同时区的日历对象实例(与当前时间)
java.util.GregorianCalendar[time=1383128400000,areFieldsSet=true,lenient=true,
zone=America/New_York,
firstDayOfWeek=1,minimalDaysInFirstWeek=1,ERA=1,YEAR=2013,MONTH=9,WEEK_OF_YEAR=44,
WEEK_OF_MONTH=5,DAY_OF_MONTH=30,DAY_OF_YEAR=303,DAY_OF_WEEK=4,
DAY_OF_WEEK_IN_MONTH=5,AM_PM=0,HOUR=6,HOUR_OF_DAY=6,MINUTE=20,SECOND=0,
MILLISECOND=0,ZONE_OFFSET=-18000000,DST_OFFSET=3600000]
我怎么做?
