Daylight Savings Time with queryTagHistory() function

This other forum poster had an answer that may help:

TimeZone Formatting in Expression

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.
