Tag history Aggregateation and Interval

I want to retrieve tag history for one year duration and every day record logged at specific time for example 10:00 AM, so I am using sample size as interval and 24 hour.
If I select the report Start Date as 1st Jan 2015 and time 12:00PM then I am getting data form “[color=#FF0000]Jan 1, 2015 7:08 AM[/color]”
If I select the report date as 1st Jan 2014 and time 12:00PM then I am getting data from “[color=#FF0000]Jan 1, 2014 12:00 PM[/color]”
I am not able to understand, why this is happening, please advice. :prayer:

I want just simple report, operator select the start date and time. Then tag history will retrieve for every 24 hour and display in table.
for example operator selects START DATE as “1st Jan 2014 10:00 AM” then report will retrieve for interval of 24 hour. Means first record will have “1st Jan 2015 10:00 AM” and 2nd record will have “2nd Jan 2015 10:00 AM” and so on and on for every day.

See below screen shot.

Are you in the US? Have you tried setting your start date to something more recent than March 8th 2015?
