Start/Finish Time

[Jack8rkin]

Hello everybody!

Help me please to select the correct lexis for the instruciton I'm translating.
The situation is as follows:
Process operations are to be performed to install certain equipment.
There is an "operation control card", as it is entitled, that is used to check if all required operations are done.
There are a number of operations and they are written in sequence on the card.
There are two lines at the bottom of the card where the time should be indicated when the operation is started and finished.

Here is the question:
What to write in these lines?
Will it be ok to write the following?
Operation start time___________
Operation end time____________

Thanks

Finish sounds better to me than end.
