设置系统时间

都是调用win api


void SetSystemInfo::on_pushButton_applyDate_clicked()
{
#ifdef Q_OS_WIN
  SYSTEMTIME sysTime;
  GetLocalTime(&sysTime);
  sysTime.wYear = ui->dateEdit->date().year();
  sysTime.wMonth = ui->dateEdit->date().month();
  sysTime.wDay = ui->dateEdit->date().day();
  SetLocalTime(&sysTime);
#endif
}
void SetSystemInfo::on_pushButton_applyTime_clicked()
{
#ifdef Q_OS_WIN
  SYSTEMTIME sysTime;
  GetLocalTime(&sysTime);
  sysTime.wHour = ui->timeEdit->time().hour();
  sysTime.wMinute = ui->timeEdit->time().minute();
  sysTime.wSecond = ui->timeEdit->time().second();
  SetLocalTime(&sysTime);
#endif
}
