alerting and time tag

What would be the proper syntax to exclude a certain time period for an alert?

I would like to have no alert every Sunday morning from 3am to 4am.

And would it be possible to disable multiple time slots, like Tuesday and Thursday between 4pm to 6pm?

Hobbit-alerts.cfg

Host=* COLOR=red TIME=0:0300:400
