Not exactly Imesh. We can do operations if operands are in the same units.
So we can do subtract operation in milliseconds. And then we can do
division operation to make it in seconds. On the other hand, we can do a
division operation to make each operands to seconds, then since both are
seconds, we can do a subtract operation. So we can apply the formula if
operands are in same unit. I guess this is same for all scenarios.

IMO, this is a sufficient solution.

Let me explain how I see Nirmal's solution.

We are taking only first and last values in a window for gradient
calculation. If there are more events in that window, and if that is a good
sample, tGap will be taking some higher values than 1s. This is usual
situation. Nirmal's fix is nothing to do with this scenario.

If there are few events in that window(say only 2), they can be really
nearer. So there is a possibility that tGap can take a value near to 0. In
that case gradient will be a very big value. Hence, if the tGap is very low
(less than 1 second), then we can assume that the first and last events
actually occurred in 1 second gap. The reason why tGap is less than 0 is,
there are only few events in that window, and that sample is not good
enough. But this a rare situation, it can only happen once in a while.
Nirmal's fix is only dealing with this scenario. Fix imposes a lower limit
in the time interval between two events. This fix is really important to
deal with samples which are not good enough.

By previous formula, we get -1000. This happened because the sample is not
good enough (may be there are few events). Fix makes it to -5.

So my understanding is that the solution is good enough for now.

Thanks.
