Time of day issue

1

Hi, I have this background that changes with a visitors time of day.

It works fine (the first run), but when I test it (by changing my clock on my desktop) it seems to just go from one frame to the next w/out actually rechecking the AS.

ActionScript Code:
[FONT=Courier New][LEFT]current = [COLOR=#0000FF]undefined[/COLOR];

[COLOR=#000000]function[/COLOR] loadNew COLOR=#000000[/COLOR] [COLOR=#000000]{[/COLOR]
container.[COLOR=#0000FF]play[/COLOR]COLOR=#000000[/COLOR];
[COLOR=#000000]}[/COLOR]

[COLOR=#000000]function[/COLOR] checkTime COLOR=#000000[/COLOR] [COLOR=#000000]{[/COLOR]
[COLOR=#0000FF]date[/COLOR] = [COLOR=#000000]new[/COLOR] [COLOR=#0000FF]Date[/COLOR]COLOR=#000000[/COLOR];
hour = [COLOR=#0000FF]date[/COLOR].[COLOR=#0000FF]getHours[/COLOR]COLOR=#000000[/COLOR];

[COLOR=#0000FF]if[/COLOR] [COLOR=#000000]([/COLOR]hour >= [COLOR=#000080]0[/COLOR] && hour <= [COLOR=#000080]8[/COLOR][COLOR=#000000])[/COLOR] [COLOR=#000000]{[/COLOR]
[COLOR=#0000FF]if[/COLOR] [COLOR=#000000]([/COLOR]current != [COLOR=#FF0000]“day”[/COLOR][COLOR=#000000])[/COLOR] [COLOR=#000000]{[/COLOR]
current = [COLOR=#FF0000]“day”[/COLOR];
loadNew COLOR=#000000[/COLOR];
[COLOR=#000000]}[/COLOR]

[COLOR=#000000]}[/COLOR] [COLOR=#0000FF]else[/COLOR] [COLOR=#0000FF]if[/COLOR] [COLOR=#000000]([/COLOR]hour >= [COLOR=#000080]9[/COLOR] && hour <= [COLOR=#000080]16[/COLOR][COLOR=#000000])[/COLOR] [COLOR=#000000]{[/COLOR]
[COLOR=#0000FF]if[/COLOR] [COLOR=#000000]([/COLOR]current != [COLOR=#FF0000]“evening”[/COLOR][COLOR=#000000])[/COLOR] [COLOR=#000000]{[/COLOR]
current = [COLOR=#FF0000]“evening”[/COLOR];
loadNew COLOR=#000000[/COLOR];
[COLOR=#000000]}[/COLOR]

[COLOR=#000000]}[/COLOR] [COLOR=#0000FF]else[/COLOR] [COLOR=#0000FF]if[/COLOR] [COLOR=#000000]([/COLOR]hour >= [COLOR=#000080]17[/COLOR] && hour <=[COLOR=#000080]23[/COLOR][COLOR=#000000])[/COLOR] [COLOR=#000000]{[/COLOR]
[COLOR=#0000FF]if[/COLOR] [COLOR=#000000]([/COLOR]current != [COLOR=#FF0000]“night”[/COLOR][COLOR=#000000])[/COLOR] [COLOR=#000000]{[/COLOR]
current = [COLOR=#FF0000]“night”[/COLOR];
loadNew COLOR=#000000[/COLOR];
[COLOR=#000000]}[/COLOR]
[COLOR=#000000]}[/COLOR]
[COLOR=#000000]}[/COLOR]
[COLOR=#0000FF]setInterval[/COLOR] [COLOR=#000000]([/COLOR]checkTime, [COLOR=#000080]1000[/COLOR][COLOR=#000000])[/COLOR];
[/LEFT]
[/FONT]

‘container’ is the mc that has the bg’s 1 in each frame

any advice would be greatly appreciated. Thx!
