My requirement is to find out how much time is being spent by sales rep while working on cases . So I need to track how much time is being spent by sales rep in creating a task record against the case.

Could anyone tell me how to find how much time spent in creating a task record against the a particular case.


  • In order to get a good answer, pls elaborate on your requirement. What do you mean by "how much time spent in creating a task record against the a particular case."? The time between Case creation and the creation of the first taks? Or the time between creation of a task and closing of the task? Oct 15, 2014 at 12:59
  • @guy, I am sorry if I was not clear. I need to have a timer functionality on the Task Create/Edit page . On the standard Task Create/Edit page, user should be able to start/stop the timer and the time difference should be saved on some custom field. So that in future , user can track how much hours he spent in working on that task. Oct 18, 2014 at 8:51

  • Was this ever resolved? None of the answers are accepted. I'm curious because I may need to achieve a similar goal in the future. Mar 5, 2015 at 23:11
  • @ProgrammableMedley I really dont think there is any good solution to achieve this unless its a custom UI. Let me know if you found anything as I am looking to achieve a similar functionality. Oct 1, 2015 at 8:13

After going over the issue rather thoroughly I believe I came up with a simple (untested) solution.

First thing, I needed was to create three custom DateTime fields on the Task object.

These fields were:

  • StartTime__c
  • EndTime__c
  • TimeElapsed__c

Now that I have the custom fields to store the time differences properly.

The next step was to create a trigger and utility to implement the time tracking functionality.

First, the trigger code:

trigger TaskTrigger on Task(before insert, before update)
        DateTime startingTimeForTimer = System.Now();

        for(Task singleTask : Trigger.new)
                singleTask.StartTime__c = startingTimeForTimer;

        List<Task> tasksThatNeedTimeRecorded = new List<Task>();

        for(Task singleTask : Trigger.new)
            if(TaskTimeTrackingHandler.NeedsToStoreTimeDifference(singleTask, Trigger.OldMap.get(singleTask.Id))
            if(TaskTimeTrackingHandler.NeedsToRestartTimer(singleTask, Trigger.OldMap.get(singleTask.Id))
                singleTask.EndTime__c = null;

        if(tasksThatNeedTimeRecorded.size() > 0)

The trigger code is straight-forward. I used some utility methods in my handler class (TaskTimeTrackingHandler) to handle logic in methods to not clutter up the trigger.

For an insert (a before insert), I will simply check to see if a Task has a Case against it. If it does have a Case against it, I start the timer by placing the System time in the StartTime__c custom field.

For updates, it is a bit trickier, although not too complex.

If the EndTime__c custom field is assigned a value, we will store it in a list to store the time differences in the TimeElapsed__c field. If the StartTime__c has changed, we will reset the timer by setting the EndTime__c to null.

Now let's look at the handler class to see the implementation of the handler methods a bit further:

public with sharing class TaskTimeTrackingHandler
    public static String CasePrefix = Case.sObjectType.getDescribe().getKeyPrefix();

    public static Boolean NeedsToTrackTime(Task newTask)
        return newTask.WhatId != null && newTask.WhatId.startsWith(CasePrefix);

    public static Boolean NeedsToStoreTimeDifference(Task newTask, Task oldTask)
        return NeedsToTrackTime(newTask) &&
            newTask.EndTime__c != null &&
            oldTask.EndTime__c == null &&
            newTask.StartTime__c != null;

    public static Boolean NeedsToRestartTimer(Task newTask, Task oldTask)
        return newTask.StartTime__c != oldTask.StartTime__c && NeedsToTrackTime(newTask);

    public static void StoreTimeDifferences(List<Task> tasksThatNeedToStoreTimeDifferences)
        for(Task singleTask : tasksThatNeedToStoreTimeDifferences)
            singleTask.TimeElapsed__c = 
                ((singleTask.TimeElapsed__c == null 
                 ? 0 : singleTask.TimeElapsed__c.getTime()) +
                (singleTask.EndTime__c.getTime() - singleTask.StartTime__c.getTime()));

    private static Boolean TaskHasCaseHours(Task singleTask)
        return NeedsToTrackTime(singleTask) && singleTask.TimeElapsed__c != null;

    public static Long GetHoursSpentOnCase(Task taskToFindHoursOnCase)
            return taskToFindHoursOnCase.TimeElapsed__c.getTime() / 1000 / 60 / 60 / 24;
        return 0;

I placed all the logic to check the Task fields in my handler for a cleaner trigger like I said before. Plus, I was able to reuse some methods, like NeedsToTrackTime.

Everything else is pretty simple now that it is broken down.

I specifically made sure that if the TimeElapsed__ field had a value, any time differences will be accumulated. This was if you consistently start and stop your timer, you will get an accumulative difference in a DateTime value.

Lastly, here is an example below on how to use the trigger to track time, with comments above each one to show what it's doing.

//To start the timer on a particular Task, simply create a Task against a Case object
INSERT taskWithCaseAgainstIt;

//To stop the timer and have the trigger record the time spent on it, simply assign a
//DateTime to the EndTime__c custom field
taskWithCaseAgainstIt.EndTime__c = System.Now();
UPDATE taskWithCaseAgainstIt;

//To restart the timer, assign a new start time (StartTime__c) to your Task with the 
//case against it and it will return the EndTime__c custom field to null.
taskWithCaseAgainstIt.StartTime__c = System.Now();
UPDATE taskWithCaseAgainstIt;

//Now if you set an end time again, the time difference will be accumulated
taskWithCaseAgainstIt.EndTime__c = System.Now();
UPDATE taskWithCaseAgainstIt;

//Now to get the hours spent on a given case, you can use the static method GetHoursSpentOnCase
Long hoursSpentOnCase = TaskTimeTrackingHandler.GetHoursSpentOnCase(taskWithCaseAgainstIt);

There is some room for improvement, such as clearing the TimeElapsed__c field should clear the StartTime__c and EndTime__c fields. Other than that, I believe this will give you the functionality you're looking for.


You can achieve this by writing a simple trigger on task:

Trigger TaskAfter on Task(After insert){
    Set<Ids> caseIds = new Set<Ids>();

    for(Task t: tigger.new) {
        if(t.whatID !=null && String.valueOf(t.whatID).substring(0,3) =='500')

    List<case> csLst = [select id,First_Task_created_date__c from Case 
        where First_Task_created_date__c=null && ID IN :caseIds];

    for (Case c : csLst ){

    update csLst;

Note: First_Task_created_date__c is a custom field to capture first task created date.

Then you can create a new formula field to calculate the number of days between Case created date and First task created date.
