the currentDateTime system tag

You are looking at it in the designer, which will use the designer's time zone. Date/time objects in Ignition are instances of java.util.Date which always carry their content as milliseconds UTC, rendering to string in whatever local timezone the code is running. The designer is a local application to your workstation, so it renders in your designer workstation's time zone. Gateway scripts (and Perspective scripts) are using the gateway's time zone for conversions to and from other formats.

You are seeing entirely expected behavior.

Note that Perspective components that are given utc milliseconds and told to render as date can display in the browser's time zone. See this topic:

Why is datetime column being converted to a number in a query?

It’s a Perspective thing. Javascript doesn’t have a datetime datatype. At bottom, Javascript has numbers and strings, so Perspective has to coerce all data into one or the other on the way to the browser. Perspective components that manipulate dates know to convert back and forth on the front end. As @victordcq pointed out, the Perspective table will also do this if you configure the column to render as a date.
