Downtime Question

[Patrick Nixon]

Okay,
 I know this is going to be an easy answer, but I'm trying to setup a
multiple downtime window for one of my services, but I can't seem to
have it kick in.

 two questions:
1   If a service is already down, when you change bb-hosts for the
downtime window, will it turn red->blue?
2   What, if anything, is wrong with this statement?
    DOWNTIME=cam:60:0000:2400,*:1930:0830

 My goal is to ignore it from 730p to 830a daily and all day saturday and sunday

 The info page shows: cam:60:0000:2400, All days:1930:0830 under the
planned downtime.

Thanks!
