Assigning tickets to an agent after business hours

Assigning tickets to an agent after business hours

Hi,

Is it possible to assign tickets to a specific agent outside our business hours (without associating it to SLA)?

I tried setting up an assignment via Setup > Automate > Assign/Route, and then selected 'Created Time' in Criteria, but I am unsure how I can incorporate the business hours.  If I select 'between', it asks me to specify a date and time.  I can specify the time, but the date is not specific as is it recurring (daily).  

Can you also confirm what 'CurrentTime' is?

Thank you!
