How do I request a new feature for next Aadroid update?

[AC Question]

How do I request a new feature for the clock that is included in Android 4.4.4 on my Moto G phone. There is a huge choice of cities for which to display the time but I want to display a time zone e.g. UTC, or MST, or CST, instead of home or instead of a city.

Display of time zones rather than cities is not supported in Clock ver 3.0.0. but it would be a very useful feature.

thanks
Andy
