Line should be black as should Load. Line comes from the source. Load to the device being controlled by the timer. There should be a white (neutral) connection (most likely) for completion of power to the clock.
I am guessing without seeing how the timer is designed and how you are tapping into the circuit. The power (hot) for the timer could be made internally from the line connection or may need a separate pigtail from the line and of course the power has to come from the line, not the load side so the clock operates continuously.
