Describe the improvement

I'd like to be able to customize the tooltip text. Specifically, I'd prefer the seconds to display in the tooltip, instead of being constantly visible.

Describe how this improvement could help users.

Some users reasonably may prefer not to have their day counted down constantly like the ticks of a clock, but still want access to seconds when needed.
