Hey guys, I am trying to display a millisecond timestamp in perspective using the browser's local timezone. Despite this, I continue to have the gateway's timezone being used, even though I explicitly defined it to use the client's timezone. Is there anything I am missing here? timezone setting: ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/c/e/ce450635aefcee807aa60a03b75424d7cbe0032d.png) property binding: ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/1/e/1ead5fc3df9aa2645f42a0c92fba68eeba60604c.png) result in browser: ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/e/a/ea80516b05a945537a119264e2b760dedb36626f.png) I expect it to show MST instead of CST. Any thoughts? ---

The transform runs on the gateway so it cheerfully ignores the project setting. As far as I can tell, the Project time zone property only applies to components where the dates get formatted automatically. A good example is the Date Time Input component. If you were to feed your milliseconds into a binding on the `value` property of one of those, you'd see the formatted date would display with the project time zone. ---

Huh, I was always under the assumption that component property bindings ran in the client scope and not the gateway scope. ---

It's Perspective, everything executes on the gateway scope. I really do wish the date functions would automatically take the project timezone into account or have a configurable time zone parameter. ---

Well I guess that makes sense. I could probably use the session TimeZoneID somehow to format the datetime into the correct timezone. ---

I obviously didn't dig hard enough. This came up once I refined my search slightly: > [@\[IGN-6614\]What is the best way to format a date (milliseconds) for a specified timezone with Ignition's python scripting](https://forum.inductiveautomation.com/t/ign-6614-what-is-the-best-way-to-format-a-date-milliseconds-for-a-specified-timezone-with-ignitions-python-scripting/64068/7): > > Ah, I was overthinking things.

Changing Project Timezone to _Client_ didn't seem to have any effect on the standard Perspective views when rendered on a browser page for me. Adding a Property Binding to the Session Props timeZoneId of `this.props.device.timezone.id` did change the presented time to the local timezone as set by the browser (chromium, developer tools, sensors, location -\> override to whatever you want to test and F5 to reload the Perspective page) ---

Once we add a timezone argument to the scripting/expression functions, it should be "easy" for us to pass through a contextual timezone automatically, and for you to override it if you have some other purpose. I'll make a note on the existing internal ticket discussed in that other thread. ---

> [@Cole\_Townsend](#): > > my final solution You really should not be doing imports in transforms (or any other `def`s where you can avoid it). Delegate to a project library utility script, like shown here: > [@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.

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… ---

I found this article which seems helpful > **[Time Zones in Perspective](https://support.inductiveautomation.com/hc/en-us/articles/17189847446797-Time-Zones-in-Perspective)** > > Introduction > This document provides guidance on how to support multiple time zones in Ignition 8.1.3 when using Perspective. A Perspective session can run with multiple different time zones simulta... There might be a clue in there about why changing Project Timezone to client didn't change anything for me. The project Component Session Property was hardcoded (by default?) to America/New York and that value overrides the Project Timezone. Maybe setting the value to "" would enable the Project Timezone setting? (Note that I haven't tested this.) Unfortunately the article starts out defining the _Perspective Session Timezone_ and discussing how it is set but then transitions to _Browser timezone_ when talking about how things are displayed. Those are not the same thing, and my experiments yesterday indicates that the components don't use _Browser timezone_, at least not the ones that I was looking at. ---

Are the module imports not cached or something when the def runs? Do you say this because it's reimporting the module every time the function runs? ---

No (the imported module itself is persistently cached, but the import statement won't find it without an expensive lock), and yes. Same with `def` nested within another `def`, mostly.
