Past Event still showing

Hi, I live in city GMT +9, and using korean.
KLWP 3.28b729710

1. Timezone>GMT+9 option actually showing time to -9:00, GMT-9 is +9:00.
maybe localizing or something's wrong.

2. "ci(Title, 0)" still showing past event. I tested GMT (calendar, system clock, KLWP setting...),
I found "ci" doesn't work on GMT setting. I changed system clock to add 9 hour.
Event showing right.

3. sometimes event date/time to showing wrong GMT. now still showing right.
but I don't know why...
