Auto-add today's date and time to new Entity title upon creation? I'd like to be able to auto-add today's date/time to the title of a particular Entity type when a new entity of that type is created. For instance, if I create an entity called "My New Entity", I'd like the title of that entity to actually be saved as "My Entity - 020513 - 103501" (assuming the entity is created on February 5, 2013, at 10:35:01 am).

Is this possible? If so, how can it be accomplished on a Drupal 7 website?

Thanks!
Option #1

For Drupal 7 you're looking at the Automatic Entity Label module if you're after a particular entity.


  "Automatic Entity Label" is a small and efficient module that allows
  hiding of entity label fields. To prevent empty labels it can be
  configured to generate the label automatically by a given pattern.


Possible option #2

Another option is available if your Entity has actions exposed to Rules.  Simple create a rul that reacts on entity creation, and set some conditions as per usual.  Then, in the actions do the following:

1) Add an action for Set data value

2) Find your entity (node for example) and look for :title under data selector (e.g. node:title)

3) Click continue

4) On the next page, set the data value to be whatever you need with tokens (so your example could be something like as [node:title] - [site:current-date])
