cita与eth的兼容性

eth与cita时间戳精度不一样，有个配置项可以选择
eth_compatibility : 是否与以太坊兼容的开关(CITA默认与以太坊在块的时间戳精度上不兼容，CITA为毫秒，以太坊为秒)。

pragma solidity 0.4.26;

contract Nervosbj {
  uint public h = 1 hours;
  uint public min = 1 minutes;
  uint public s = 1 seconds;

  function timeNow ()
    public
    view
    returns (uint)
  {
    return block.timestamp;
  }

  function happyTime()
    public
    view
    returns (uint, uint, uint)
  {
    uint now = block.timestamp;
    return (now+s, now+min, now+h);
  }

}
