Post From: NEGATIVE bar time duration

I'm using CVB (Constant Volume Bars) for e-mini ES and NQ futures.
I need to calculate the velocity of the volume in lots/sec, but I have a problem with the bar time duration when volumes run very fast:
as you can see from the attached pictures (highlighted by the ellipses) the bar time duration in some cases became negative and obviously this is not possible.

Is it possible to solve this issue?

Waiting for your kind reply.
