Just noticed that wordpress’ time needs to configure to local time zone, eg. +10 for Sydney, otherwise it will show a wrong time like the time in the notes I posted before. I haven’t figured out if wordpress does day light saving automatically, for now, I have to put in +11 instead of +10 to adjust to the right time.
I ajusted the time by loging into my account in wordpress, then Options>General and added +11 to the space after “Times in the weblog should differ by”, it’s working nicely.
