Dave,
I found this article and used it to download, compile and install the new files. I'm guessing that the data oacs uses is derived from this data. I do know that I followed the instructions and the 'time' on several computers changed to the new timezone.
This data can change at any time (and there is a newer update than mentioned in the above article), and it includes all timezones, so the difficulty becomes how to update an SQL database.
You might also note that the only thing changing here is timezones. It is a mistake to change the time and not the timezone. Changing time is an actual error. A timezone is simply an offset from GMT, which is never adjusted (timezone +0.00).
