Question about Date () class

[FONT=Calibri][SIZE=3]How hard would be to do something like this?[/SIZE][/FONT]
[FONT=Calibri][SIZE=3]I am doing a project where two movieClips need to be manipulated with the date class (sun_mc and moon_mc). [/SIZE][/FONT]
[FONT=Calibri][SIZE=3]
What I want to do is show the sun_mc at 7:00 am and hide moon_mc, and at 8:00pm I want to do the opposite (show moon_mc and hide sun_mc).[/SIZE][/FONT]
[FONT=Calibri][SIZE=3]Thanks,[/SIZE][/FONT]
