Update Checker

[n1ksn]

I think you could leave the minutes and hours boxes as-is (although they could be horizontally smaller) but just put "Minutes" and "Hours" in front of them (to their left).  Then put a text line above the two saying "Time between checks" (or your favorite wording). 

Or maybe better, under the description line put the two boxes on the same line, (smaller, of course), with the simple hour and minute labels beneath or above them and a big "+" sign or ":" colon between them.
