Is there better documentation for stringformat() the 7.9 and 8.0 manuals are really lacking in an explanation in the manual. What string format parameters are available and what do they do?

Yeah, there’s better documentation. It appears to use Java’s String.format() under the hood. Which uses [java.util.Formatter](https://docs.oracle.com/javase/8/docs/api/java/util/Formatter.html) in turn. Fwiw, I prefer its **%t** conversions over Ignition’s dateFormat() function.
