You can create both Attributes and Expressions which are dates.
For a 'Date' attributes go to...
File -> Properties -> Attributes
...and set the 'Data Type' to 'Date' and you will be given today's date but you can edit it to be whatever value you wish.
As for expressions, you can find a 'Date' function under the
[f(x)] button.
But be aware that these date functions have a slightly different behavior. The 'date' expression will update to the current date everytime the model updates, which can be a useful piece of information if you somehow wanted to embed some time sensitive behavior into your model. However, if you're looking for something like a 'timestamp' that once created does not change, then stick with the 'date' attribute. Note that I can create an Expression linked to the value of the 'date' attribute and THAT Expression would not change when the model updates unless someone explicitly edited the value of the Attribute, which can be prevented if you predefine this attribute to be locked upon saving the file for the first time.
And of course, once these Attributes and/or Expressions are defined, they can be used to drive the value of a note or a field in a Tabular Note or Title Block.
