In Piwik Dashboard for Super Users,
I click on Visitors --> Visitor Log,
I choose a Date Range --> 2011-04-04,
Today's logs do not show up although the date for today is 2011-04-04.
Instead, if I click on 2011-04-03,
It shows 2011-04-04's logs. It seems you have to pick yesterday's date to show today's logs.. it is weird.
Currently using: Piwik 1.2.1
Timezone for all websites used in the dashboard: Asia/Singapore
