display/hide time on hour icon when mobile size

[eebbesen]

When on a mobile device there's not currently a way to view the times a happy hour deal is valid for.

Consider

• displaying on long touch, but finger may obscure time
• displaying on first touch, then hiding on second touch

Not sure if a popup or just replacing the clock/moving the clock makes more sense
