Date/ Time Display in Chart Window

 
Dear colleques,
is it somehow possible, to display the time on the bottom of the chart window, without the date? It would be awesome, if somebody could help me. I know, it is just a little thing, but I really could not find the answer.

It looks like that right now:

and I just want it to say like "4:35" without the date ("15 Mar") beside it.

Thank you very much
