this will work.I have tried both gave one day unique bucket.
I just realized, If I sync all clients to one zone then date will remain
same for all.
One Zone date will give materialize view to row.

Hello List,
I need suggestion/ recommendation on time series data.
I have requirement where users belongs to different timezone and they can
subscribe to global group.
When users at specific timezone send update to group it is available to
every user in different timezone.
I am using
Don't use dates or datestamps as the buckets for your row keys, use a unix
timestamp modulo whatever size you want your bucket to be instead.
Timestamps don't involve time zones or any of that nonsense.
So, instead of having keys like user1uuid_30042012, the second half would
be replaced the
thanks tyler for reply.
are you saying user1uuid_*{ts%86400}* would lead to unique day bucket
which will be timezone {NZ to US} independent? I will try.

Correct, that's exactly what I'm saying.

I did it with node.js but it is changing after some interval.
code
setInterval(function(){
var d =new Date().getTime();
console.log(== );
console.log(unix = ,d);
i=parseInt(d)
console.log(Divid i/86400= ,i/86400);
console.log(Modulo i%86400= ,i%86400);
getTime() returns the number of milliseconds since the epoch, not the
number of seconds: http://www.w3schools.com/jsref/jsref_gettime.asp
If you divide that number by 1000, it should work.

thanks I didn't noticed.
run script for 5 minutes = divide seems to produce result ,modulo is
still changing. If divide is ok will do the trick.
I will run this script on Singapore, East coast server, and New delhi
server whole night today.

Err, sorry, I should have said ts - (ts % 86400). Integer division does
something similar.
