GMT 6 is Midnight here in India. So please continue GMT 4...........
But what about people in other countries.
I think giving ppl 48 hrs time should be enough. 24 hrs or less is too difficult because of that...
24 hours is just right i think!
Not if you want to give everybody a fair chance.
If you take into account timezones, you will see that you need a lot more then 24 hrs !
