I've created a table which has three columns and five rows.
Each row stands for a specific task.
One of these columns, the third column, is dedicated to the time that I have spent to fulfill the task's obligations.
Now what should I write at the header of the third column?
My options are:
1) spent time
2) consumed time
3) taken time
I know it is very common to say "It takes me X hours to finish the task". However, I need a very compact phrase that exactly conveys the same information. Thanks
