In Coda, time is a first-class citizen. As you're getting started, we recommend starting to explore the following formulas:
Returns the current date
Returns the current time
Returns the timestamp for when something was created (E.g. 12/6/2016 1:46:48 PM)
The timestamp for when something was last modified (E.g. 12/8/2016 3:27:12 PM)
Remember, these formulas can be used both in tables and on the writing canvas!
