Trigger Run Outside of Business Hours

Question

I have my simple trigger working now where once a threshold is met for cases created within 60 minutes it updates the "SendAlert" field so my workflow can start going to work.

The next steps I am trying to figure out is if it is possible to only have this occur during non-business hours?

trigger OutageAlert on Case (before insert) {
date today =system.today();
List<Case> numberofcases = [SELECT ID FROM CASE where SLA__c<=:1];
    for(case cas:trigger.new){
        if(cas.origin == 'Web - Email'){
            if(numberofcases.size() == 5) {
                cas.SendAlert__c = true;
            }
            if(numberofcases.size() == 10) {
                cas.SendAlert__c = true;
            }
        }
    }
}

How can I add a function into this where it will only run during non-business hours?

Clarification: I want the field SendAlert__c to not go active while in business hours, is this possible in a workflow maybe since its not possible in the trigger?

If you've defined your business hours in metadata, you should be able to use the isWithin function to determine if the current datetime (DateTime.Now()) is within those defined business hours.

From the documentation:

public static Boolean BusinessHours.isWithin(String businessHoursId, Datetime targetDate) 

Returns true if the specified target date occurs within business hours. Holidays are included in the calculation.

BusinessHours bh = [SELECT Id FROM BusinessHours WHERE IsDefault=true];

if (BusinessHours.isWithin(bh.Id, DateTime.now())) {
  // Handle
} else {
  // Handle another way
}
