To be honest, I don't think any program should randomly close itself, until explicitly asked to (for example, timeout in settings). I also don't remember such "feature" in original worldclock, and this is a replacement, so it should not force such "features" in user (if no option to disable it), yep?

Not to mention, that - due to random nature of this "feature" - I'm quite convinced it is in fact a bug, segfaulting or whatsnot. Not a "feature" I would love to have.

Not demanding anything, just saying.
