A lot of triggers that i use have functions other then "last", and notifications like "Average load is {ITEM.LASTVALUE}" don't make sense when trigger actually uses "avg" function. I can't use {host:key.func(param)}, because if i will change a trigger i might forget to change notifications.

So i've written small and dirty patch that adds this macro. Currently it uses time(NULL) for function evaluation, any suggestions on how i can extract triggers "lastchange" that is usually used for function evaluation are welcome.

I am not experienced in low level programming and i've already put this in production, so any code analysis would be very welcome.
