I have just done this, and times that aren't over an hour all change to orange toogo to conditional format dialog and choose your format the type this formula
=$j1>=0.0416666666666667
does this cells have clock only ??? or clock + day date ??I have just done this, and times that aren't over an hour all change to orange too
=--TEXT($J7,"HH:MM")>=0.0416666666666667
because it extract time only not the date.Thank you very much, don't understand why it works but thank you
