CALL_FOR_TIME_FROM is used to indicate when the additional work is set to begin. This field is used when a call is recorded to a worker requesting them to work additional time.
If a worker is called and a call log is recorded where work is either "accepted" or is a "call In" (Call status) then the date and time provided below is used to create a time exception that will be processed to directly adjust the workers schedule for both scheduled and non-scheduled work.
