limit the hours available

[yabasha]

Question

I want to set limit for hours from current time, I want to make an app the gives short period of time to interact with it from the time of setting the time value

For example: from Date.now() to display hours or allow to select 4 hours, so if now is 7 it will show 8, 9, 10, and 11 so user can only select from those hours.

Please Advice,
