How to Calculate overall time duration on case form

[mania]

Hi,

I have a requirement, I have a field called Time worked once I click to start play button beside the Time worked field the time should be run and once I close the case form it should stop the time automatically and the calculate overall time and added to the Time worked Tab.

I have tried a lot but not getting proper solution.

Can you please anyone suggest script for that. It will be helpful.

Thanks in Advance!

Hi @mania 00:00 means mid night?

When agent opens the case, time should not start automatically. He should be able to manually start the timer and the timer starts. If the user/agent is updating the ticket, and the time worked is 00:00:00, add a info message (Please fill the time worked before updating the ticket) and abort the action.

I have stopped the timer automatically but  I need script for that remaining part.

Can you please help on that, It will be helpful.

Thanks!
