The "is less than or equal to" filter is in fact a "is less than" filter

[GoogleCodeExporter]

What steps will reproduce the problem?
1. In an existing project and task, start Time Tracker and stop it.
2. Click Today in the left pane so that you see the time recorded.
3. Select Custom in the left pane, and enter "startTime is greater than or 
equal to" as filter, and specify the date of the recorded time.
4. Create a second filter with "endTime is less than equal to", and enter the 
same date,

Let's say your time was recorde on 2014-06-22. If for the two filters you 
specified that date, you would expect to see your working time appear in the 
bottom pane, but it won't. You have to increase the end date by one day in 
order to see it. So the filter is really a "is less than" filter.

I am using Tiem Tracker v1.3.12 on a late 2011 Macbook Pro running OS X 
Maverick.
