Unable to display 23 seconds (or any non 10-multiples) in edit window

Is your feature request related to a problem? Please describe.

Before app update, many of my workouts are not multiples of 10 seconds (old version made it very convenient to adjust workout times in steps of 1 second). After updating to 1.13.0, duration of these workouts cannot be displayed in edit window unless I tab on the time.

Describe the solution you'd like

Some possible solutions:

1. Two independent numeric sliders resulting in a 2-digits workout time.
2. A circle clock appears after tapping the time, similar to alarm clock in Android.
