change-time: Improve prompt wording

Browse Source 
Adjust prompt wording when entering fields.  Technically the desired
value isn't always between min/max, because min and max are also
acceptable :)

No need to repeat an incorrect value, it is right there on the screen
and it dilutes the important point describing what value is needed.
