This is a very rare case but I'll try to explain.
The STARTTIME was on 11.30.2016 9:00 PM and the STOPTIME was on 12.01.2016 01:00 AM.
When I'm choosing november, to calculate the minutes between 9:00 PM an 12:00 PM isn't a problem.
But when I'm choosing december, there aren't any data, because the Month-Value is from STARTTIME.
Because of that, I think, I should split this data into two rows. The first row has the following field-data:
STARTDATE = 11.30.2016 9:00 PM
STOPDATA = 11.30.2016 12:00 PM
The second row:
STARTDATE = 12.01.2016 00:00 AM
STOPDATE = 12.01.2016 01:00 AM
Then I can select data in december.
Maybe there ist another possibility?
