iex's Issues

Error thrown from periodic callback: KeyError('time',)

This is working, and it's cool, but I'm getting a message every second to the console:

2017-07-19 10:13:59,397 Error thrown from periodic callback: KeyError('time',)
2017-07-19 10:14:00,396 Error thrown from periodic callback: KeyError('time',)
2017-07-19 10:14:01,400 Error thrown from periodic callback: KeyError('time',)
2017-07-19 10:14:02,398 Error thrown from periodic callback: KeyError('time',)
2017-07-19 10:14:03,399 Error thrown from periodic callback: KeyError('time',)

Is that to be expected?

I'm on windows, if that matters:
