GetLastVisitDetails API Method

Hello Team,

I am working with a API method ''GetLastVisitDetails".

My query looks something like this "website/module=API&method=Live.getLastVisitsDetails&idSite=1&period=day&date=2013-06-24&format=JSON/tokenKey". This is returning me a JSON object. But while parsing I noticed, even though I am querying for the date 2013-06-24. This is returning me some additional logs dated to 2013-06-23 aka previous day. Any help?

Thanks
Ritwik
