User Story:
As a user, I like to configure an interval for the starting/stopping times, so that WorkingHours clocks my work in that intervals so that I don't have to adjust the intervals later.
Explanation
Most time tracking software require the users to insert the work in intervals, mostly half hours as the smallest intervals, some allow quarter hours, even if importing the hours.
Acceptance Criteria
- UI offers the possibility to chose my rounding method (round up, round down, round up/down)
- UI lets me chose (or insert?) the rounding interval, at least the most common (15mins, 30mins, 60mins)
- WorkingHours sets the "starting time" and "ending time" within those intervals (every 15mins, every 30mins, every 60mins, ...), when using the "start work" and "stop work" functions
- WorkingHours of course uses the interval for the duration calculation already
- WorkingHours also suggests the interval, when using the "add working unit"
