Use Java's `ZonedDateTime`. Ignition's datetime objects are `java.util.Date` which are fundamentally UTC under the hood, with no attached time zone. Which means they **always** use the time zone of the JVM when parsing or printing. When you manipulate them with `.addHours()`, you are not making a time zone correction, but are altering the underlying UTC value. Don't use `.addHours()` to make time zone corrections.

But I would move the complexity to a project script module with a DateTimeFormatter instance with your preferred pattern saved as a top level variable. Like so, perhaps: from java.time import ZoneId from java.time.format import DateTimeFormatter defaultFormatter = DateTimeFormatter.ofPattern("YYYY-MM-dd HH:mm") def zonedFormat(ts, zoneid, format=None): formatter = defaultFormatter if format is None else DateTimeFormatter.ofPattern(format) r…

Note also that `DateTimeFormatter` can parse, too.
