Only trigger on weekday?

[illumin8]

I'm trying to setup a trigger that will only go true if it is a weekday, between certain hours. The time period part is easy, but I can't figure out how to do the weekday part.

I am using Zabbix 1.0.

Thanks in advance.

It looks like in Zabbix 1.1 alpha there is a "weekday" expression, but I don't think it's available in 1.0, or if it is, it's not documented.

The "weekday" is supported by 1.1 only.
