Coupon available date

To whom it may concern,

I am new to MarketPress plugin and testing all the functions.

I am located UTC+8 timezone and it has been adjusted on Wordpress setting.

When I create a new coupon with current local date and time, it just appear "RED" and not available on both admin and user sites.

Do I need to specific the timezone setting on Marketpress? and where is it?

Or I must enter the "start date" a date before today to make it available?

Looking for quick solution! Thank you!
