Clock is reset to UTC after file upload with the web IDE

I guess there may be an issue if you have a nonzero timezone and then you get time from GPS? Not sure...

what is "The GPS Time app"

Go to https://banglejs.com/apps/, look up GPS Time

can we have event emitter...

I feel like that would probably end up being a bit of a waste of battery life if Bangle.js is having to fire off events whether they are being used or not? While modules aren't handled well at the moment, there is already http://www.espruino.com/Cron which looks like it'd do a good job.
