Setting a Window for Triggers

[Jeff]

If it is possible, would someone show me how to configure
Triggers to only be "active/valid" for certain window of time?

For example, assuming that I only want to monitor if a webserver is up
between the hours of 9AM and 5PM Monday to Friday.

Thanks,
Jeff

Hours between 9am and 5pm. Not so sure about how to get M - F.
