Agreed on complexity increasing with varying timestamp formats. For this reason, I'm looking to make the workflow as simplistic and easy as possible - even at the cost of flexibility. Whatever timestamp format is easier to read into a script that then spits out the formatted text I have in my original comment, I'll go with it. Unless, of course, the timestamp format is something really long to type out like: "Mon, 15 Mar 2021 23:25:30 +0000"
