This other forum poster had an answer that _may help_:

> [@TimeZone Formatting in Expression](http://forum.inductiveautomation.com/t/timezone-formatting-in-expression/26760):
>
> Our gateway is based in PDT but most of our clients are in EDT. In the designer, we can select Perspective\>Project Timezone to be either America/New\_York or Client Timezone. The Perspective timeZoneID changes appropriately and the now() function returns the correct time. However, if I use dateFormat(now(), ‘z’), I’ll get PDT and any time will be shown in PDT. Am I missing something?

This should only be an aid to understanding what is happening, from there it is up to you.
