Usually it's a timezone issue with the local os clock, since that's what we read.

If you type (into the console):

Code:

d(os.date("!%H"))

It should give you the proper UTC time, which should be the correct offset away from your computer's time.

Additionally, you should be able to do:

Code:

d(AddHours(<insertTheUTCHourFromAbove>,9)

And if you google for "JST time", the number here should correspond to the current time in JST.
