Bugs in the DateTimeUtil::getSystemDateTime()

After the current system date is changed, either from the user interface or via systemDateSet function, the DateTimeUtil::getSystemDateTime() goes out of control. Don't ever use this function for unique keys generation.

Unfortunately, they use it a lot in the DIXF.

static void printDateTimeJob(Args _args)
{
    void printDateTime()
    {
        info(strFmt('systemDateGet: %1 %2', 
            systemDateGet(), 
            time2StrHMS(timeNow())));
        info(strFmt('getSystemDateTime: %1', DateTimeUtil::getSystemDateTime()));
        info(strFmt('utcNow: %1', DateTimeUtil::utcNow()));
    }
 
    warning('Before date/time change');
 
    printDateTime();
 
    sleep(2000);
 
    info('...2 seconds later:');
 
    printDateTime();
 
    systemDateSet(systemDateGet() - 3);
 
    warning('System date changed:');
 
    printDateTime();
 
    sleep(2000);
 
    info('...2 seconds later:');
 
    printDateTime();
 
    systemDateSet(systemDateGet() + 3);
 
    warning('System date is back:');
 
    printDateTime();
 
    sleep(2000);
 
    info('...2 seconds later:');
 
    printDateTime();
}

And this is the result:
