Bugs in the DateTimeUtil::getSystemDateTime()

网络文摘 William 333浏览 0评论
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:
