Great App for when you really want to know PRECISELY what time it is, to set your watch to the exact second, for instance. Simple yet very useful.

I love it and I don't mind the adds but could you please trim the app down, it's a little larger compared to others with the exact same functions at only .5-3mb. Kinda always tight on space it would be appreciated.

Unlike many others that report the incorrect time. But I hate banner ads!
