Showing "Since x days" information in the cards

[rajanpsanthanam]

What is this about?
Showing "Since x days" information in the card. Currently there is no information on for how long a card is part of a list

Why is this important?
I think it can be an important metric for anyone to know how long a card is being in a list before getting moved to different list.

Say this can answer questions like

how long is this card pending in backlog?
how many days passed since we started the implementation on this?
how long is this getting tested?
how much time it spent on due for deployment?
