Different Pivots with different brokers

Hi,
i have two demo accts. with alpari and activtrades. Both with MT4, both with the same templates and the same pivot-indicator (from imran).
I have the same settings within the indis, but they show me two different pivot points !! How can this be ?
Can you help me ?
I.e. today the pivot line in the EURUSD is at activtrades 1,4643 in alpari it is 1,4605

What pivot do you have for today in EURUSD ?

Hi, from what i understand lah......different broker have different pivot point because :-

1. Different DATA FEED
2. Different TIME

hehe...just my 2sen lah

OK, i understand.
Somebody from US has another time than a european or asian.
I can´t do anything about the data feed. So:
But which Pivot is then the "right" one, concerning the time ?
