INT((DATEPART('hour',[Time])*60*60+DATEPART('minute',[Time])*60+DATEPART('second',[Time]))/[Time Interval])
(This formula separate data into groups based on the seconds time interval defined in parameter above, and [Time] is the time field need to be customized)
2. Create a Calculated Field named [Customized Internal Time] and input the Formula:
{ FIXED [Time Group]: MIN([Time]) }
3. Drag [Customized Internal Time] to [Pages].
