  • 描述:此类用于取得当前日期相对应的月初,月末,季初,季末,年初,年末,返回值均为String字符串
  • 1、得到当前日期 today()
  • 2、得到当前月份月初 thisMonth()
  • 3、得到当前月份月底 thisMonthEnd()
  • 4、得到当前季度季初 thisSeason()
  • 5、得到当前季度季末 thisSeasonEnd()
  • 6、得到当前年份年初 thisYear()
  • 7、得到当前年份年底 thisYearEnd()
  • 8、判断输入年份是否为闰年 leapYear
  • 注意事项: 日期格式为:xxxx-yy-zz (eg: 2007-12-05)
