Time vs Number in calculation

[Quebec City]

Hello,

My problem is, I have 2 time fields, "Begin Job" and "End Job", I also have a number field "cost"

I want to calculate (End Job - Begin Job) and * (cost)...

But I don't know how to calculate number and time field??

I need help!!!

Thanks!

Time is stored as the number of seconds past midnight. So, you can simply subtract one time from the other to get a number of seconds. To convert to hours, divide by 3600.

(End Job - Begin Job) /3600 * Cost

Assuming cost is $/hour

If the job starts on one day and ends on another then you need to account for that:

((End Job Day - Begin Job Day)*24 + (End Job - Begin Job) /3600) * Cost
