earn has not same with post date?

You have to bear in mind that Malaysia is 13 hours ahead of Kansas in the US. You can check the date and time you are posting (according to MyLot) by looking at the bottom of every page where it says 'myLot time: ....'. If you post something in the morning (up to 1pm, your time), it will show up as posted the previous day. Also, of course, there is a 24 hour delay before earnings show up for a particular day, so what you post on a Monday will not show up until Wednesday. Once you get your head round the time differences, it is not too difficult to understand. Most people give up worrying about it after a bit!
