automatic time stamp and field age

automatic time stamp and field age

Hi,

I am trying to note the time when a certain field is updated in Zoho CRM.

I've been able to create a rule that would trigger the respective field update. However, for the field where I'd like the current time stamp to be automatically recorded, I'm not being able to add a dynamically generated time. I can only add some static text.

Is there a way to dynamically generate time stamps?

Subsequently, I'd like to know how to show the age of the field once I've generated the time stamp (for e.g.2 months 3 days old). 

Thanks,
