Then use the techniques in this post to **display** timestamps in any desired timezone (instead of `session.props.timezoneId`): > [@Ignition Perspective Page to show the client System date and time](https://forum.inductiveautomation.com/t/ignition-perspective-page-to-show-the-client-system-date-and-time/73265/8): > > Sure.

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… --- _[View the full topic](https://forum.inductiveautomation.com/t/installing-pytz-library/94123)._
