In case it is of any help to anyone, my toolbox document (ref. forum post ) includes a technical Note with the name “Date/Time handling in Tinderbox” that provides a list of examples for how to assemble dates and times using various built-in methods. It is by no means complete, but I put this together as a crib sheet for my project work, and I often refer to it. Perhaps others might find this helpful. If anyone wants to suggest additions to this crib sheet, I will gladly add them to future updates.
