I am building intervals using 0.5h increments (1800sec) in a cycle. The 
interval length is 1800sec also

8:30 am is used as start date.

last of my interval looks like this:

[2009-Apr-07 14:30:00/2009-Apr-07 14:59:59.999999]

because of this weired endpoint my data with the timestamp of 
Apr-07 15:00:0000 does not fit into the interval

How can I fix the interval to be
[2009-Apr-07 14:30:00/2009-Apr-07 15:00:000000] ?

Thanks
