And I'm not sure what updates you are talking 
about.  Got some examples?

I see updates occurring at every hour of the day. 
 I catch some, others I don't.  What kind of 
pattern are you seeing?  If I had to make a 
generalization, updates on the East Coast happen 
in the evening, so we are more likely to be awake 
and catch them.  And Japan is 16 hours ahead of 
us, so forget trying to make any assumptions about 
their update times relative to a specific time 
zone over here.

If you really want to catch updates so badly, I 
have two suggestions:
1) It seems like you are talking about certain 
sites with certain prices---have you tried 
e-mailing them to ask about future site updates.  
Nick, of Animechaos, is an example of someone who 
regularly posts very accurate predictions of his 
update times.
2) This may sound simple, but check sites more 
often.  Even a slow internet connection like mine 
can allow me to do a quick check of the Keep Track 
page in a couple of minutes.  And I can crawl out 
of bed and spare those two minutes without harming 
my sleep.  If you really watch a site (like you 
seem to be) you can probably predict the hour of 
the day they will update, so you can set your 
clock.

I hope that was as constructive as you wanted.

It would help people take you more seriously if 
you use your real name, IMHO.

In short, don't rant about your time zone.  Learn 
and adapt.

Good luck.
