Task Creation Duration Selection

[Dinith1]

User Story:

As a user, I want an easy way to pick a valid (non-negative) duration for my task, so that it can be added to my schedule with no problems.

Acceptance Criteria:

1. The selection of task duration should be similar to that of the date/time, i.e. use some sort of dial to select number of hours/number of minutes
2. The number of hours/minutes able to be selected should be a sensible number, e.g. 0-99 hours, and 0-59 minutes

Something like this would be nice (but probably without seconds)

Why is the feature required?

• Currently, the user has to enter a duration via the keyboard or up/down buttons
• The user can enter a negative duration (BUG)
