I have a milliseconds-since-local-epoch timestamp that I'd like to convert into a milliseconds-since-UTC-epoch timestamp. From a quick glance through the docs it looks like something like this would work:

int offset = TimeZone.getDefault().getRawOffset();
long newTime = oldTime - offset;

Is there a better way to do this?
