"Search meeting date and time" API

Hi everyone,
Good Morning!

Let me ask one question about "Search meeting date and time" api. I would like to know that api can search the available meeting with different date or not. Now, im trying to search with different date as per below, but i cant and the api response is only for this date 2016-05-20T07:00:00.

{

"Attendees": [
{
"Type": "Required",
"EmailAddress": {
"Name": "Fanny",
"Address": "xxxxxx@prosewareltd.onmicrosoft.com"
}
}
],
"TimeConstraint": {
"ActivityDomain":"Work",
"Timeslots": [
{
"Start": {
"DateTime": "2016-05-20T07:00:00",
"TimeZone": "Pacific Standard Time"
},
"End": {
"DateTime": "2016-05-25T17:00:00",
"TimeZone": "Pacific Standard Time"
}
}
]
},
"MeetingDuration": "PT1H"
}

If you have any idea, please advise me.
With Thanks
