You can use tod and dow variables to create flexible vectors that evaluate factors, such as hours and days of week, so an appropriate call treatment is delivered to customers.

You can use global collect variables to define call center start and close times for different days of the week. The collect variables provide threshold values that are tested against tod and dow values to determine appropriate call treatments.

You can set up special VDNs to reassign variable values for the opening and closing time. For instance, when a change in daylight saving time occurs. The new variable values are instantly propagated to any number of vectors in which the variables are used.
