Thanks.

If you really want to change the (system) timezone, I don't think Qt libraries offer a call for that. You would need to do it via some other C++/OS-specific system call.

If all you want to do is convert datetimes across timezones Qt has QTimeZone Class.

Is it possible for me to do this conversion using the QTimeZone class and make it permanent for the application?

No, as I said there is no static void QTimeZone::setTimeZone() function.

There are C library calls like tzset() which work off an (TZ?) environment variable you could alter. But I do not know which Qt or other libraries calls use that versus a more native timezone OS call.
