feature request against system.tag.queryTagHistory

Won't be possible. Datasets from this function contain java.util.Date objects that don't have a timezone. You have to do it yourself when stringifying the result for the WebDev output. Presuming you know the target timezone, use this procedure:

Update the perspective date component as per system date

Yes, your scripts can take the UTC milliseconds from the java.util.Date Ignition uses and make a java.time.Instant with its static method .ofEpochMilli(). Then, obtain a java.time.ZoneId, usuallly by lookup with .of(). With those two, you can obtain a java.time.ZonedDateTime with its .ofInstant() method. That can then be formatted numerous ways, all respecting the given ZoneId.
